Correct Answer: B

Rationale: The correct answer is to check the heart rate first before administering digoxin. Digoxin is a medication that directly affects the heart, so it is crucial to ensure that the heart rate is within the appropriate range before giving the dose. If the heart rate is below 60 bpm, administering digoxin could lead to toxicity. Assessing blood pressure (Choice A) is important but not the first priority when preparing to administer digoxin. Monitoring potassium levels (Choice C) is also crucial for patients on digoxin, but it is not the initial step. Reviewing the medication order (Choice D) is necessary but can be done after checking the heart rate.

Correct Answer: D

Rationale: Clients with renal failure are at risk for electrolyte imbalances and hypertension. Monitoring electrolyte levels is crucial because renal failure can lead to imbalances in sodium, potassium, and other electrolytes. Blood pressure monitoring is essential as hypertension is a common complication of renal failure. Therefore, both electrolyte levels and blood pressure should be closely monitored to detect and manage any abnormalities. Fluid intake, while important, is not specific to renal failure monitoring and is not the priority in this case.

Correct Answer: A

Rationale: Corrected Rationale: The client with a cystocele should perform Kegel exercises to strengthen the pelvic floor muscles, reducing the risk of pelvic organ prolapse and stress urinary incontinence. Kegel exercises specifically target the muscles that support the pelvic organs. Isometric exercises focus on static muscle contractions and may not be as effective as Kegel exercises for strengthening the pelvic floor. Circumduction exercises involve circular movements at joints and are not specific to pelvic floor muscle strengthening. Uterine extension exercises do not directly target the pelvic floor muscles and are not indicated for cystocele management.

Correct Answer: A

Rationale: The correct answer is to assess for mood changes. When administering escitalopram, it is crucial to evaluate mood changes first because the medication may take some time to demonstrate its full effects on the patient's mood. Assessing blood pressure, heart rate, or liver function is not the priority when administering escitalopram, as these parameters are not directly impacted acutely by this medication.

Correct Answer: A

Rationale: Before administering blood products, assessing the patient's temperature is crucial. This action provides baseline data to detect any febrile reactions during or after the transfusion. Fever may indicate a transfusion reaction, so continuous monitoring of vital signs is essential throughout the procedure. Documenting the patient's response (choice B) is important but comes after assessing the temperature. Priming IV tubing with 0.45% sodium chloride (choice C) is not directly related to the initial action required before administering blood products. Administering epinephrine (choice D) is not indicated unless there is a severe allergic reaction, which is not the standard initial step before blood product administration.
