A patient with hypertension is prescribed lisinopril. What side effect should the nurse monitor for?
- A. Hyperkalemia
- B. Hypoglycemia
- C. Bradycardia
- D. Constipation
Correct Answer: A
Rationale: The correct answer is A: Hyperkalemia. Lisinopril is an ACE inhibitor that can cause potassium retention, leading to hyperkalemia. Monitoring potassium levels is crucial to prevent serious complications like cardiac arrhythmias. Hypoglycemia (B) is not a common side effect of lisinopril. Bradycardia (C) and constipation (D) are also not typically associated with lisinopril use. Hyperkalemia is the most critical side effect to monitor in this case.

A patient with atrial fibrillation is prescribed warfarin. Which laboratory test should the nurse monitor to assess the effectiveness of the medication?
- A. Complete blood count (CBC)
- B. Prothrombin time (PT)/INR
- C. Partial thromboplastin time (PTT)
- D. Serum potassium level
Correct Answer: B
Rationale: The correct answer is B: Prothrombin time (PT)/INR. This is because warfarin is a medication that affects the clotting ability of the blood by inhibiting vitamin K-dependent clotting factors. PT/INR is the specific laboratory test used to monitor the effectiveness of warfarin therapy. PT measures how long it takes for blood to clot, while INR standardizes the PT results. Monitoring PT/INR helps to ensure that the patient is within the target therapeutic range for anticoagulation.
Incorrect choices:
A: Complete blood count (CBC) - CBC does not directly assess the effectiveness of warfarin therapy.
C: Partial thromboplastin time (PTT) - PTT is used to monitor the effectiveness of heparin therapy, not warfarin.
D: Serum potassium level - Monitoring serum potassium level is not directly related to assessing the effectiveness of warfarin therapy.
An outcome for treatment of peripheral vascular disease is, 'The client will have decreased venous congestion.' What client behavior would indicate to the nurse that this outcome has been met?
- A. Avoids prolonged sitting or standing.
- B. Avoids trauma and irritation to skin.
- C. Wears protective shoes.
- D. Quits smoking.
Correct Answer: A
Rationale: The correct answer is A because avoiding prolonged sitting or standing helps improve venous return by preventing blood from pooling in the legs, reducing venous congestion. This behavior promotes circulation and decreases the risk of complications. Choices B, C, and D do not directly address venous congestion or circulation improvement, making them incorrect options. Avoiding trauma and irritation to the skin (B) is important for skin integrity but not specifically for venous congestion. Wearing protective shoes (C) is related to preventing foot injuries but does not directly impact venous congestion. Quitting smoking (D) is beneficial for overall health but does not directly target venous congestion.
A patient with diabetes insipidus is prescribed desmopressin. What is the primary purpose of this medication?
- A. Increase urine output
- B. Reduce blood sugar levels
- C. Decrease urine output
- D. Lower blood pressure
Correct Answer: C
Rationale: Desmopressin is a synthetic form of vasopressin used to replace the hormone in diabetes insipidus. The primary purpose is to decrease urine output by increasing water reabsorption in the kidneys, thereby reducing excessive urination and preventing dehydration. Choice A is incorrect as desmopressin actually decreases urine output. Choice B is incorrect as desmopressin does not directly affect blood sugar levels. Choice D is incorrect as desmopressin does not primarily lower blood pressure.
A patient with chronic pain is prescribed a fentanyl patch. What is the most important instruction for the nurse to provide?
- A. Apply the patch to a different site each time.
- B. Change the patch every 72 hours.
- C. Avoid using additional heating pads over the patch.
- D. Remove the patch before showering.
Correct Answer: B
Rationale: The correct answer is B: Change the patch every 72 hours. Fentanyl patches are typically designed to be worn for 72 hours before being replaced to maintain consistent pain relief. Changing the patch on time helps prevent withdrawal symptoms and ensures the effectiveness of the medication.
A: Applying the patch to a different site each time is important to prevent skin irritation but is not the most crucial instruction.
C: Avoiding heating pads over the patch is important to prevent overheating and excessive absorption of the medication, but changing the patch timely is more critical.
D: Removing the patch before showering is not necessary as fentanyl patches are designed to be water-resistant.
For a patient with asthma, what is the primary purpose of prescribing salmeterol?
- A. Relieve acute bronchospasm
- B. Prevent asthma attacks
- C. Suppress cough
- D. Thin respiratory secretions
Correct Answer: B
Rationale: The primary purpose of prescribing salmeterol is to prevent asthma attacks. Salmeterol is a long-acting beta agonist that helps to relax the muscles of the airways over an extended period, reducing the likelihood of bronchospasms and asthma exacerbations. It is not used for relieving acute bronchospasm (choice A), suppressing cough (choice C), or thinning respiratory secretions (choice D) as these are not the main therapeutic effects of salmeterol in asthma management.
