Question 1
Regular
A nurse teaches clients at a community center about risks for dehydration. Which client is at greatest risk for dehydration?
Correct!
Incorrect
The correct answer is: C
Rationale
A 75-year-old who is cognitively impaired is at greatest risk for dehydration. Cognitive impairment often leads to decreased awareness of thirst and challenges in recognizing the need for fluid intake, making this population particularly vulnerable to dehydration. Additionally, older adults generally have diminished physiological responses to fluid balance, compounding the risk further.
A: A 36-year-old who is prescribed long-term steroid therapy may experience fluid retention rather than dehydration, as steroids can alter fluid balance and increase water retention in the body.
B: A 55-year-old receiving hypertonic intravenous fluids is being provided with extra fluid, which typically helps prevent dehydration rather than increasing the risk of it occurring.
D: A 63-year-old with congestive heart failure may be monitored for fluid overload, and while this condition can complicate hydration, it does not inherently increase dehydration risk.

Question 2
Regular
A nurse is caring for a client who exhibits dehydration-induced confusion. Which intervention should the nurse implement first?
Correct!
Incorrect
The correct answer is: D
Rationale
D: Increase oral fluid intake. Addressing dehydration is paramount in managing confusion, as restoring fluid balance directly impacts cognitive function and overall health, making it the most immediate intervention for the nurse to undertake.
A: Measure the client's pulse and blood pressure. While important for assessing vital signs, this action does not directly address the dehydration causing the client's confusion and delays critical intervention.
B: A 5-year-old who is cognitively impaired. This option is irrelevant to the scenario, as it pertains to a specific age group and cognitive condition rather than addressing dehydration in the client.
C: Applying oxygen by mask or nasal cannula. Although oxygen may assist in certain situations, it does not resolve dehydration, which is the primary issue causing the client's confusion and requires urgent attention.

Question 3
Regular
A nurse assesses a client who is prescribed a medication that inhibits angiotensin I from converting into angiotensin II (angiotensin-converting enzyme; [ACE] inhibitor). For which expected therapeutic effect should the nurse assess?
Correct!
Incorrect
The correct answer is: A
Rationale
Blood pressure decrease from 180/72 mm Hg to 144/50 mm Hg. ACE inhibitors function by preventing the conversion of angiotensin I to angiotensin II, resulting in vasodilation and reduced blood pressure, thus achieving the desired therapeutic effect of hypertension management.
B: Daily weight increase from 55 kg to 57 kg. An increase in weight does not correlate with the primary therapeutic goal of ACE inhibitors, which is to lower blood pressure, not affect weight.
C: Heart rate decrease from 100 beats/min to 80 beats/min. While heart rate may be influenced by blood pressure changes, ACE inhibitors primarily target blood pressure reduction, not directly modify heart rate.
D: Respiratory rate increase from 12 breaths/min to 15 breaths/min. Respiratory rate changes are unrelated to the action of ACE inhibitors, which focus on cardiovascular effects rather than respiratory function.

Question 4
Regular
A nurse is assessing clients on a medical-surgical unit. Which adult client should the nurse identify as being at greatest risk for insensible water loss?
Correct!
Incorrect
The correct answer is: A
Rationale
Client with fever and rapid respirations. Elevated body temperature and increased respiratory rate significantly heighten insensible water loss, making this client particularly vulnerable to dehydration and electrolyte imbalances.
B: Client with diabetes mellitus. While diabetes can impact fluid balance, the risk for insensible water loss is not as pronounced as with fever and rapid breathing.
C: Client receiving intravenous isotonic fluids. This client is receiving adequate hydration through IV fluids, reducing the likelihood of insensible water loss compared to other conditions.
D: Client with stable heart failure. Stable heart failure usually involves fluid retention rather than loss, making this client less susceptible to insensible water loss compared to those with fever.
Correct Answer: A

Question 5
Regular
A nurse is assessing clients for fluid and electrolyte imbalances. Which client should the nurse assess first for potential hyponatremia?
Correct!
Incorrect
The correct answer is: A
Rationale
Client receiving 5% dextrose in water (D5W) intravenously and is NPO. This client is at high risk for hyponatremia due to fluid overload and lack of sodium intake while being NPO, necessitating immediate assessment.
B: A 34-year-old with an infection who is prescribed a sulfonamide antibiotic. While infections can lead to electrolyte imbalances, sulfonamide antibiotics do not specifically increase the risk of hyponatremia.
C: A 67-year-old who is experiencing pain and is prescribed ibuprofen (Motrin). Ibuprofen primarily addresses pain; it does not contribute significantly to sodium levels or fluid imbalances in this context.
D: A 73-year-old with tachycardia who is receiving digoxin (Lanoxin). Although digoxin is critical for cardiac function, it does not directly impact sodium levels, making this client's assessment less urgent for hyponatremia.

Question 6
Regular
A nurse teaches a client who is at risk for mild hyponatremia. Which statement should the nurse include in this client's teaching?
Correct!
Incorrect
The correct answer is: C
Rationale
C: Read food labels to determine sodium content. Monitoring sodium intake through food labels helps the client manage their sodium levels effectively, which is crucial for preventing mild hyponatremia and maintaining electrolyte balance.
A: Weigh yourself every morning and every night. While monitoring weight can provide some insights into fluid retention, it does not directly address sodium intake or prevention of hyponatremia.
B: A 3-year-old with a client who is prescribed a sulfonamide antibiotic. This option is unrelated to the client's risk for mild hyponatremia and does not provide relevant dietary guidance for sodium management.
D: Bake and grill to treat rather than frying it. Although healthier cooking methods are beneficial, this statement does not specifically address sodium intake or its role in preventing hyponatremia.

Question 7
Regular
Which meal choice is most appropriate for a client on a low-sodium diet?
Correct!
Incorrect
The correct answer is: D
Rationale
Grilled chicken breast with glazed carrots is the most appropriate meal choice for a client on a low-sodium diet. This option features lean protein and vegetables, both typically low in sodium, aligning with dietary restrictions.
A: Ham sandwich with mustard contains processed meat and condiments, which often have high sodium content, making it unsuitable for a low-sodium diet.
B: Tomato soup with crackers frequently includes added salt for flavor, contributing to elevated sodium levels, thus not ideal for someone needing to limit sodium intake.
C: Spaghetti with meat sauce often incorporates salty ingredients like cheese or processed meats, leading to a higher sodium content, contrary to the requirements of a low-sodium diet.

Question 8
Regular
A nurse is caring for a client who has the following laboratory results: potassium 3.4 mEq/L, magnesium 1.8 mEq/L, calcium 8.5 mEq/L, sodium 144 mEq/L. Which assessment should the nurse complete first?
Correct!
Incorrect
The correct answer is: B
Rationale
B: Depth of respirations
Assessing the depth of respirations is critical due to the potential effects of electrolyte imbalances, particularly low potassium and magnesium levels, which can significantly impact respiratory function and overall stability.
A: Bowel sounds
Evaluating bowel sounds does not take precedence in this scenario, as respiratory assessment directly correlates to the immediate risks posed by the client's electrolyte levels.
C: Grip strength
While grip strength is important for overall neuromuscular function, it is not as urgent as assessing respiratory depth when electrolyte imbalances may compromise the client's breathing.
D: Electrocardiography
Although electrocardiography is essential for monitoring cardiac status, it follows the priority of evaluating respiratory function, which can be adversely affected by the current electrolyte levels.

Question 9
Regular
A nurse cares for a client who has a serum potassium of 7.5 mEq/L and is exhibiting cardiovascular changes. Which prescription should the nurse implement first?
Correct!
Incorrect
The correct answer is: C
Rationale
C: Prepare to administer dextrose 20% and 10 units of regular insulin IV push. This intervention is crucial as it rapidly lowers serum potassium levels by facilitating potassium's movement into cells, thus addressing the immediate cardiovascular risks associated with hyperkalemia.
A: Prepare to administer sodium polystyrene sulfonate (Kayexalate) 15 g by mouth. While this medication helps reduce potassium levels, it acts more slowly than insulin and dextrose, delaying essential treatment.
B: Provide a client healthy, low potassium diet. Although dietary management is important for long-term potassium control, it does not address the immediate and severe hyperkalemia affecting the client’s cardiovascular status.
D: Prepare the client for hemodialysis treatment. Hemodialysis is a definitive treatment for severe hyperkalemia, but it is more time-consuming and not the first-line immediate intervention needed in this acute situation.

Question 10
Regular
A nurse is assessing a client on a medical-surgical unit. Which client is at risk for hypokalemia?
Correct!
Incorrect
The correct answer is: A
Rationale
A: Client with pancreatitis who has continuous nasogastric suctioning
Continuous nasogastric suctioning can lead to significant loss of gastric fluids, which in turn reduces potassium levels in the body, making the client vulnerable to hypokalemia.
B: Client with a prescription for an angiotensin-converting enzyme (ACE) inhibitor
While ACE inhibitors can affect potassium levels, they typically lead to hyperkalemia rather than hypokalemia, particularly in clients with healthy renal function.
C: Client in a motor vehicle crash who is receiving 2 units of packed red blood cells
Receiving blood transfusions does not inherently affect potassium levels, and this scenario does not present a clear risk for hypokalemia related to the transfusion itself.
D: Client with uncontrolled diabetes and a serum pH level of 7.33
Uncontrolled diabetes may lead to metabolic acidosis, which can actually preserve potassium levels rather than deplete them, thus not indicating a hypokalemic risk.

Question 11
Regular
A nurse is assessing a client with hypokalemia, and notes that the client's handgrip strength has diminished since the previous assessment 1 hour ago. Which action should the nurse take first?
Correct!
Incorrect
The correct answer is: A
Rationale
Assess the client's respiratory rate, rhythm, and depth.
Hypokalemia can lead to muscle weakness, affecting respiratory muscles. The nurse must prioritize assessing respiratory function to ensure the client can breathe adequately and prevent serious complications.
B: Measure the client's pulse and blood pressure. While vital signs are important, the immediate concern is the potential respiratory compromise due to diminished handgrip strength.
C: Document findings and monitor the client. Documentation is essential but does not address the urgent need to assess respiratory status related to possible hypokalemia effects.
D: Contact the health care provider. This action may be necessary later, but immediate assessment of respiratory function takes precedence to prevent further deterioration of the client's condition.

Question 12
Regular
After teaching a client to increase dietary potassium intake, a nurse assesses the client's understanding. Which dietary meal selection indicates the client correctly understands the teaching?
Correct!
Incorrect
The correct answer is: C
Rationale
C: Sausage, whole-wheat toast, half cup of raisins, and a glass of milk. This meal selection showcases a high potassium content primarily due to the raisins, which significantly contribute to the dietary potassium intake that the nurse aimed to educate the client about, demonstrating their understanding of the dietary recommendations.
A: Toasted English muffin with butter and blueberry jam, and tea with sugar. This meal lacks potassium-rich foods, failing to meet the dietary increase needed for effective potassium intake.
B: Two scrambled eggs, a slice of white toast, and a half cup of strawberries. While strawberries contain potassium, this meal overall does not provide sufficient potassium-rich options for the client's needs.
D: Bowl of oatmeal with brown sugar, a half cup of sliced peaches, and coffee. Although peaches have some potassium, this meal doesn't include enough potassium sources to reflect the client's understanding of dietary changes.

Question 13
Regular
A client at risk for developing hyperkalemia states, 'I love fruit and usually eat it every day, but now I can't because of my high potassium level.' How should the nurse respond?
Correct!
Incorrect
The correct answer is: C
Rationale
C: Berries, cherries, apples, and peaches are low in potassium. These fruits contain significantly less potassium compared to other fruits, making them suitable options for someone managing high potassium levels while still enjoying fruit.
A: Potatoes and avocados can be substituted for fruit. Both potatoes and avocados are actually high in potassium, which does not provide a safe alternative for someone at risk of hyperkalemia.
B: Fruit is universally high in potassium. While many fruits are high in potassium, this statement overlooks the fact that some fruits are low and can be safely consumed.
D: You are correct. Fruit is very high in potassium. This generalization fails to acknowledge that there are specific fruits that have lower potassium content, which can be safely enjoyed.

Question 14
Regular
A nurse is caring for a client who has a serum calcium level of 14 mg/dL. Which provider order should the nurse implement first?
Correct!
Incorrect
The correct answer is: B
Rationale
Connect the client to a cardiac monitor. High serum calcium levels can lead to cardiac complications, making continuous monitoring essential to detect potential arrhythmias or other critical changes in heart function promptly.
A: Encourage oral fluid intake. While hydration is important for managing hypercalcemia, it does not address the immediate risk of cardiac complications associated with elevated calcium levels.
C: Assess the client's urine output. Although urine output is relevant for monitoring kidney function, it does not prioritize the urgent need to observe cardiac status in this scenario.
D: Administer oral calcitonin (Calcimar). Administering calcitonin may help lower calcium levels, but immediate cardiac monitoring takes precedence to ensure the client's safety and manage potential life-threatening arrhythmias.

Question 15
Regular
A nurse is caring for an older adult client who is admitted with moderate dehydration. Which intervention should the nurse implement to prevent injury while in the hospital?
Correct!
Incorrect
The correct answer is: D
Rationale
Dangle the client on the bedside before ambulating. This intervention helps the client adjust to an upright position gradually, reducing the risk of falls and injury due to potential dizziness from dehydration.
A: Ask family members to speak quietly to keep the client calm. While this may promote a soothing environment, it does not directly address the risk of physical injury associated with dehydration.
B: Assess the client's mental status daily. Although important for overall care, this intervention does not directly mitigate the physical risks of dehydration, such as falls or injuries during ambulation.
C: Encourage the client to drink at least 1 liter of fluids each shift. While hydration is vital, simply increasing intake does not ensure the client's safety when transitioning to upright positions.
Correct Answer: D

A nurse develops a plan of care for a client who has a history of hypokalemia. Which interventions should be included in this client's care plan? (Select all that apply.)
Correct!
Incorrect
The correct answer is: B,D
Rationale
B: Use a draw sheet to reposition the client in bed. This intervention minimizes the risk of injury due to muscle weakness associated with hypokalemia, ensuring safe and effective mobility for the client.
A: Encourage oral fluid intake of at least 2 L/day. While hydration is important, this option does not specifically address the management of hypokalemia or its associated risks.
C: Monitor serum potassium levels daily. Although monitoring is essential, it alone does not provide an immediate intervention to manage or prevent the effects of hypokalemia.
E: Rotate the client from side to side every 2 hours. This action does not directly relate to addressing the specific needs of a client with hypokalemia, which focuses more on safety and support.
