A physician has prescribed bumetanide for a client with high blood pressure who also has renal insufficiency. Which of the following instructions should the nurse include in the teaching plan for this client?
Correct!
Incorrect
The correct answer is: B
Rationale
Avoid salt substitutes containing potassium. Patients on bumetanide may experience decreased potassium levels, and using potassium-rich substitutes can lead to hyperkalemia, worsening renal function and increasing cardiovascular risks.
A: Avoid salt substitutes containing potassium. While potassium management is crucial, the primary concern with bumetanide is monitoring overall drug interactions, not solely potassium intake through substitutes.
C: Always take the drug before meals. Timing of bumetanide administration relative to meals is not critical; the focus should be on adherence and monitoring fluid balance, not meal schedules.
D: Omit the drug dose when feeling dizzy. Dizziness could indicate dehydration or hypotension from bumetanide use, but omitting the dose without professional guidance may lead to poor blood pressure control.
Correct Answer: B
Rationale: Avoid salt substitutes containing potassium. Patients on bumetanide may experience decreased potassium levels, and using potassium-rich substitutes can lead to hyperkalemia, worsening renal function and increasing cardiovascular risks.
A: Avoid salt substitutes containing potassium. While potassium management is crucial, the primary concern with bumetanide is monitoring overall drug interactions, not solely potassium intake through substitutes.
C: Always take the drug before meals. Timing of bumetanide administration relative to meals is not critical; the focus should be on adherence and monitoring fluid balance, not meal schedules.
D: Omit the drug dose when feeling dizzy. Dizziness could indicate dehydration or hypotension from bumetanide use, but omitting the dose without professional guidance may lead to poor blood pressure control.
Question 23
Regular
A nurse is caring for a client with increased intraocular pressure who is receiving urea. After administering the drug, the nurse would assess the client for which of the following?
Correct!
Incorrect
The correct answer is: A
Rationale
A: Syncope. Urea can lead to rapid shifts in fluid balance, potentially causing hypotension and syncope due to decreased blood volume or changes in electrolyte levels, which warrants careful monitoring after administration.
B: Cramping. While cramping can occur with electrolyte imbalances, it is not specifically associated with urea administration and is less likely to be a primary concern in this scenario.
C: Photosensitivity. Photosensitivity is not a recognized side effect of urea, as this medication primarily targets fluid management and pressure reduction, rather than influencing light sensitivity in the client.
D: Blurred vision. Although increased intraocular pressure may cause visual disturbances, blurred vision is not a direct consequence of urea therapy and does not typically require immediate assessment after its administration.
Correct Answer: A
Rationale: A: Syncope. Urea can lead to rapid shifts in fluid balance, potentially causing hypotension and syncope due to decreased blood volume or changes in electrolyte levels, which warrants careful monitoring after administration.
B: Cramping. While cramping can occur with electrolyte imbalances, it is not specifically associated with urea administration and is less likely to be a primary concern in this scenario.

Question 24
Regular
A nurse is preparing to administer spironolactone to a client. The nurse would contact the primary health care provider about the need to change the order if the client has a history of which of the following?
Correct!
Incorrect
The correct answer is: A
Rationale
Spironolactone is contraindicated in clients with hyperkalemia due to its potassium-sparing properties, which can exacerbate elevated potassium levels, potentially leading to serious cardiac complications and other health risks.
B: Liver disease. While liver disease can affect drug metabolism, it does not pose an immediate risk when administering spironolactone compared to hyperkalemia, which directly impacts potassium balance.
C: Gout. Spironolactone does not specifically interact negatively with gout; however, it can increase uric acid levels, but this is less critical than the danger of hyperkalemia.
D: Diabetes. Although diabetes requires careful management of medications, spironolactone does not have a direct contraindication for diabetic patients, making it less relevant than the risk associated with hyperkalemia.
Correct Answer: A
Rationale: Spironolactone is contraindicated in clients with hyperkalemia due to its potassium-sparing properties, which can exacerbate elevated potassium levels, potentially leading to serious cardiac complications and other health risks.

Question 25
Regular
A nurse is caring for a client with edema due to congestive heart failure (CHF). The primary health care provider has prescribed indapamide. The client is also receiving digoxin. Which intervention would be most appropriate for the nurse to implement?
Correct!
Incorrect
The correct answer is: C
Rationale
C: Frequently monitor the client's pulse rate and rhythm. Monitoring the pulse is critical due to digoxin's potential effects on heart rhythm and rate, especially in clients with congestive heart failure who may experience complications.
A: Encourage oral fluids at frequent intervals during waking hours. Increased fluid intake may exacerbate edema in clients with CHF, contrary to the goal of managing fluid retention effectively.
B: Encourage the client to eat or drink between meals and in the evening. This may lead to excessive calorie intake or fluid retention, which is counterproductive for managing CHF symptoms.
D: Closely monitor the client for signs of hyperkalemia. While important, hyperkalemia monitoring is not the top priority in this context given the primary worry regarding digoxin's effects on the heart.
Correct Answer: C
Rationale: C: Frequently monitor the client's pulse rate and rhythm. Monitoring the pulse is critical due to digoxin's potential effects on heart rhythm and rate, especially in clients with congestive heart failure who may experience complications.

Question 26
Regular
A nurse administers a thiazide diuretic to a client with renal compromise as prescribed by the primary health care provider. Which action by the nurse would be most appropriate if the client's blood urea nitrogen level increases?
Correct!
Incorrect
The correct answer is: B
Rationale
Withholding the next dose of the drug is the most appropriate action. An increased blood urea nitrogen level indicates potential worsening renal function, necessitating a reevaluation of the medication's use to prevent further complications.
A: Give prescribed magnesium supplements. Administering magnesium supplements does not address the underlying issue of renal compromise and may exacerbate the condition due to potential electrolyte imbalances.
C: Administer the drug in a diluted form. Diluting the medication does not mitigate the risk associated with renal impairment and might still lead to adverse effects on the client's health.
D: Increase the fluid intake for the client. While hydration is important, simply increasing fluid intake does not solve the problem of elevated blood urea nitrogen and may not be sufficient intervention.

Question 27
Regular
A primary health care provider has prescribed a loop diuretic for a client with hypertension. The client also has diabetes mellitus. The nurse would assess the client for which of the following after administering the drug?
Correct!
Incorrect
The correct answer is: B
Rationale
Increased blood glucose levels. Loop diuretics can affect glucose metabolism, potentially leading to elevated blood sugar levels, especially in clients with diabetes mellitus, necessitating careful monitoring after administration.
A: Sudden pain in the joints. Joint pain can indicate various conditions but is not a direct effect of loop diuretics, making this option irrelevant in this context.
C: Occurrence of gout attacks. While loop diuretics can elevate uric acid levels, the immediate concern after administration is monitoring blood glucose, not the risk of gout attacks.
D: Sudden increase in weight. An increase in weight may indicate fluid retention or other issues, but loop diuretics primarily promote weight loss through fluid elimination, not sudden weight gain.
Correct Answer: B

Question 28
Regular
A client is prescribed a diuretic that is to be taken twice a day. When instructing the client about the schedule for administration, the nurse would suggest that the client take the drug at which times?
Correct!
Incorrect
The correct answer is: C
Rationale
C: At breakfast and midafternoon. Taking the diuretic in the morning and midafternoon allows for effective management of fluid balance while minimizing nighttime urination, which promotes better sleep and adherence to the medication schedule.
A: In the early morning and at bedtime. This schedule risks increased nighttime urination, disrupting sleep and potentially leading to noncompliance with the medication regimen.
B: After lunch and dinner. Administering the diuretic too late in the day can cause excessive urination during the night, which is inconvenient and may hinder restful sleep.
D: Midmorning and before dinner. Taking the medication at these times may not optimize fluid management throughout the day, leading to ineffective control of fluid retention and possible discomfort.
Correct Answer: C
Rationale: C: At breakfast and midafternoon. Taking the diuretic in the morning and midafternoon allows for effective management of fluid balance while minimizing nighttime urination, which promotes better sleep and adherence to the medication schedule.

Question 29
Regular
A client who is receiving diuretic therapy comes to the clinic for a follow-up visit. The client states that his mouth is often dry and that he is 'urinating like there is no tomorrow.' Assessment reveals dry mucous membranes and decreased skin turgor. Which nursing diagnosis would the nurse most likely identify?
Correct!
Incorrect
The correct answer is: B
Rationale
Risk for Deficient Fluid Volume.
The client exhibits signs of dehydration, such as dry mucous membranes and decreased skin turgor, which are indicative of insufficient fluid volume due to diuretic therapy. This diagnosis directly addresses the fluid imbalance and the client’s symptoms.
A: Risk for Injury. Potential falls or accidents could occur, but the primary concern in this scenario is the evident fluid volume deficiency rather than injury risk.
C: Impaired Urinary Elimination. While increased urination is noted, the primary issue is fluid volume depletion rather than a direct impairment in the urinary elimination process.
D: Deficient Knowledge. The client’s symptoms point to a physiological issue rather than a lack of understanding about their condition or treatment, making this option irrelevant in this context.

Question 30
Multiple Choice
A nurse is reviewing the laboratory test results of a client who is receiving diuretic therapy. The nurse determines that the client is at risk for electrolyte imbalance based on which results? Select all that apply.
Correct!
Incorrect
The correct answer is: D,E
Rationale
D: Sodium 124 mEq/L, E: Potassium 2.9 mEq/L. Both results indicate significant electrolyte imbalances; sodium levels are critically low, leading to potential neurological issues, while low potassium can cause cardiac complications, confirming the client's risk during diuretic therapy.
A: Potassium 4.5 mEq/L. This potassium level falls within the normal range, indicating no immediate risk for imbalance related to potassium deficiency or excess.
B: Sodium 139 mEq/L. This sodium measurement is also within normal limits, suggesting no significant risk of hyponatremia or related complications in the client’s electrolyte status.
C: Magnesium 2.0 mEq/L. The magnesium level is within the acceptable range, indicating that there is no concern for magnesium deficiency or excess affecting the client’s overall electrolyte balance.

Question 31
Regular
A client is receiving mannitol as treatment to promote diuresis in acute renal failure. The nurse would expect to administer the drug by which route?
Correct!
Incorrect
The correct answer is: C
Rationale
C: Intravenously. Mannitol is typically administered intravenously to ensure rapid onset of action, essential for promoting diuresis in acute renal failure, as it allows precise dosing and immediate therapeutic effects.
A: Intramuscularly. This route does not provide the rapid absorption needed for mannitol's effects in acute renal failure and can lead to inconsistent plasma levels.
B: Subcutaneously. Administering mannitol subcutaneously would result in slow absorption, delaying the intended diuretic effect and potentially leading to inadequate therapeutic response in acute renal failure.
D: Orally. Oral administration of mannitol is ineffective for acute renal failure treatment, as it may not achieve the necessary plasma concentration quickly enough to promote diuresis.
