Question 1
Multiple Choice
You will expect to find which of the following during the skin assessment of a patient with dehydration?
Correct!
Incorrect
The correct answer is: B,E
Rationale
Dryness and prolonged skin tenting are expected findings during the skin assessment of a patient with dehydration. These signs indicate a lack of moisture and impaired skin elasticity, both indicative of dehydration.
A: Redness indicates inflammation or irritation, which is not a typical sign of dehydration. Instead, dehydration primarily manifests through a lack of moisture in the skin.
C: Dependent edema suggests fluid retention and is more commonly associated with conditions like heart failure or kidney issues, rather than dehydration, which typically results in dry skin.
D: Blisters are indicative of skin injury or infections, rather than dehydration. Dehydrated skin usually presents as dry and flaky without the formation of blisters.

Question 2
Multiple Choice
The nurse is completing an I&O sheet for the patient. Which will the nurse include in the output?
Correct!
Incorrect
The correct answer is: C,D,F
Rationale
Liquid stool, emesis, and urine are all considered outputs that the nurse should include in the I&O sheet for the patient. These fluids are significant indicators of the patient's hydration status and gastrointestinal function.
A: Sweat Sweat is typically considered insensible loss and not usually documented in an I&O sheet focused on measurable outputs.
B: Peritoneal fluid Peritoneal fluid is not part of standard output measurements in I&O documentation, as it is not excreted in a measurable way by the patient.
E: Interstitial fluid Interstitial fluid is not directly measurable through conventional I&O methods and does not represent a tangible output that can be included on an I&O sheet.

Question 3
Regular
The patient complains of shortness of breath and is expectorating pink frothy sputum. The nurse would assess for further signs and symptoms of:
Correct!
Incorrect
The correct answer is: C
Rationale
Fluid overload. The patient's expectoration of pink frothy sputum and shortness of breath indicates pulmonary congestion, often associated with excess fluid in the lungs, necessitating further assessment for fluid overload signs.
A: hyperkalemia Elevated potassium levels do not typically present with respiratory symptoms or pink frothy sputum, making this option irrelevant to the patient's condition.
B: hypomagnesemia Low magnesium levels are unlikely to cause shortness of breath or sputum production, as they primarily affect neuromuscular function rather than fluid balance in the lungs.
D: fluid deficit A lack of fluid would not contribute to the observed symptoms; instead, it would typically result in different manifestations such as dehydration rather than pulmonary congestion.
E: dehydration Dehydration typically leads to dry mucous membranes and decreased urine output, not the pulmonary symptoms and frothy sputum observed in this patient.

Question 4
Regular
When teaching a patient about ways to avoid fluid overload, the nurse explains it is best to eat a diet that is low in:
Correct!
Incorrect
The correct answer is: D
Rationale
A diet low in sodium is best for avoiding fluid overload. Sodium retention can lead to increased fluid retention and higher blood pressure, exacerbating conditions like heart failure and kidney disease. Reducing sodium intake helps manage fluid balance effectively, making it crucial in dietary recommendations for patients at risk of fluid overload.
A: potassium High potassium levels are often monitored but do not directly cause fluid retention, making dietary restrictions less critical in preventing overload compared to sodium intake.
B: calcium Calcium does not significantly influence fluid balance or retention, so dietary restrictions on calcium are not essential for patients trying to avoid fluid overload.
C: magnesium While magnesium plays a role in various bodily functions, its dietary restriction does not have a direct impact on fluid balance and overload concerns for patients.
E: phosphorus Phosphorus levels are important for bone health, but they do not have a primary association with fluid retention or overload issues in the context of dietary management.

Question 5
Regular
You know that your patient with chronic kidney disease will need more teaching if she says:
Correct!
Incorrect
The correct answer is: A
Rationale
I will eat more oranges to prevent potassium buildup. Eating more oranges can lead to excessive potassium intake, which is particularly concerning for patients with chronic kidney disease who need to limit potassium consumption to avoid complications.
B: I will increase my milk intake to keep my calcium levels in the normal range. While calcium is important, excessive milk consumption can lead to high phosphorus levels, which can exacerbate kidney issues.
C: I will avoid bananas so my potassium level will not get too high. This statement demonstrates understanding as bananas are high in potassium, making avoidance necessary for managing potassium levels in chronic kidney disease.
D: I can have scrambled eggs for breakfast as long as my calcium is not too high. While eggs are low in potassium, this statement overlooks the broader dietary restrictions needed for chronic kidney disease management.

Question 6
Regular
Your patient has a low potassium level, uncorrected by oral medications. The physician orders 30 mEq of KCl added to the IV of 1,000 mL of normal saline to infuse at 80 mL per hour. Which nursing intervention is of the most importance to perform today?
Correct!
Incorrect
The correct answer is: D
Rationale
D: Make certain urine output is at least 30 mL per hour. Ensuring adequate urine output is vital when administering potassium intravenously, as it helps prevent potential complications like hyperkalemia and ensures proper renal function during treatment.
A: Serve a diet with potassium-rich foods. While dietary potassium is important, the immediate focus should be on monitoring urine output during IV potassium administration for safety.
B: Restrict sodium in the diet. Sodium restriction does not directly address the urgent need for monitoring potassium levels and urine output, which are critical in this patient's treatment.
C: Monitor blood levels of all electrolytes. Although electrolyte monitoring is essential, prioritizing urine output specifically addresses the safety concerns associated with potassium infusion, making it the more critical intervention.
E: Monitor for fever and tachypnea. While these signs may indicate infection or complications, they are not as directly related to the management of potassium infusion as urine output monitoring.

Question 7
Regular
Your patient is admitted with alkalosis. Which laboratory finding would you expect?
Correct!
Incorrect
The correct answer is: B
Rationale
pH of 7.48
Alkalosis is characterized by an elevated pH level, typically above 7.45. A pH of 7.48 indicates a state of alkalosis, aligning with the expected laboratory findings in this condition.
A: pH of 7.30
A pH of 7.30 reflects acidosis, contradicting the definition of alkalosis, which demands a higher pH level, typically above 7.45.
C: Decreased bicarbonate level
In alkalosis, bicarbonate levels are usually elevated as the body attempts to compensate. A decreased bicarbonate level does not align with the biochemical profile of alkalosis.
D: Elevated carbon dioxide level
Elevated carbon dioxide levels generally indicate respiratory acidosis rather than alkalosis. In alkalosis, carbon dioxide levels are often decreased due to hyperventilation and respiratory compensation.
Correct Answer: B

Question 8
Multiple Choice
Which is true of respiratory acidosis?
Correct!
Incorrect
The correct answer is: B,D
Rationale
Respiratory acidosis occurs when the patient is hypoventilating. This condition leads to an accumulation of carbon dioxide in the bloodstream, resulting in a decrease in blood pH below 7.35, indicating acidosis.
A: The patient is hyperventilating. Hyperventilation results in excessive exhalation of carbon dioxide, which would raise the pH, contrasting the characteristics of respiratory acidosis.
C: This causes the pH to elevate above 7.45. An increase in pH above 7.45 indicates alkalosis, not acidosis, which is characterized by a decrease in pH below 7.35.
F: Hypokalemia. This electrolyte imbalance refers to low potassium levels in the blood and does not directly correlate with respiratory acidosis, which primarily involves carbon dioxide retention.
G: Hyperchloremia. Elevated chloride levels do not signify respiratory acidosis and are unrelated to the respiratory mechanisms influencing blood pH in this condition.

Question 9
Regular
If a patient's blood pH is 7.33, the patient is in:
Correct!
Incorrect
The correct answer is: B
Rationale
The patient is in acidosis. A blood pH of 7.33 indicates a decrease in alkalinity, signifying an acidic environment in the body, which can disrupt normal physiological functions and requires medical attention.
A: alkalosis A blood pH of 7.33 reflects acidity, not alkalinity, which is characteristic of alkalosis, where the pH is typically above 7.45, indicating an opposite condition.
C: hypovolemic shock Blood pH does not specifically diagnose hypovolemic shock, as this condition relates to low blood volume rather than acid-base balance, making this option irrelevant to the pH reading.
D: a state of dehydration Dehydration primarily affects fluid balance and electrolyte levels, not blood pH directly. A low pH reading does not indicate dehydration but rather suggests acid-base imbalance.
