1. A client has a new prescription for spironolactone. The client should avoid which of the following foods?

A. Salt substitutes
B. Apples
C. Chicken
D. Bananas

Correct answer: A

Rationale: Spironolactone is a potassium-sparing diuretic. Clients prescribed spironolactone should avoid salt substitutes because they often contain potassium. Increased potassium intake can lead to hyperkalemia, which is a potential side effect of spironolactone.

2. A client with deep vein thrombosis has been on heparin continuous infusion for 5 days. The provider prescribes warfarin PO without discontinuing the heparin. The client asks the nurse why both anticoagulants are necessary. Which of the following statements should the nurse make?

A. Warfarin takes several days to work, so the IV heparin will be used until the warfarin reaches a therapeutic level.
B. I will call the provider to get a prescription for discontinuing the IV heparin today.
C. Both heparin and warfarin work together to dissolve the clots.
D. The IV heparin increases the effects of the warfarin and decreases the length of your hospital stay.

Correct answer: A

Rationale: The correct answer is A because warfarin takes several days to reach a therapeutic level and exert its full anticoagulant effect. During this time, the IV heparin is continued to prevent clotting until the warfarin is effective. Both medications are used together temporarily for this reason. Discontinuing heparin prematurely can increase the risk of clot formation. Therefore, the nurse should explain to the client that the IV heparin will be continued until the warfarin reaches a therapeutic level.

3. Which of the following conditions is not treated with epinephrine?

A. Renal disease
B. Asthma
C. Hypotension
D. Glaucoma

Correct answer: A

Rationale: Epinephrine is not used to treat renal disease. Epinephrine is commonly used to treat conditions like asthma, hypotension, and glaucoma, but it is not an appropriate treatment for renal disease. Renal disease requires specific management strategies that do not involve the use of epinephrine.

4. A client has a new prescription for Raltegravir. Which of the following statements should the nurse include in teaching the client?

A. This medication prevents the virus from entering the cell.
B. This medication prevents the virus from leaving the cell.
C. This medication blocks the virus from attaching to the cell.
D. This medication blocks the virus from replicating in the cell.

Correct answer: D

Rationale: The correct answer is D because Raltegravir works by blocking the integrase enzyme, preventing the virus from integrating its genetic material into the host cell's DNA. By inhibiting this process, viral replication within the host cell is halted. Choices A, B, and C are incorrect because Raltegravir's mechanism of action specifically targets viral replication within the cell, not virus entry, exit, or attachment to the cell.

5. When administering Phenytoin, what should you monitor?

A. Behavior
B. Therapeutic blood levels
C. For signs of Stevens-Johnson syndrome
D. All of the above

Correct answer: D

Rationale: When administering Phenytoin, monitoring the patient's behavior is important to assess for any changes that may indicate adverse effects. Monitoring therapeutic blood levels helps ensure the medication is within the effective range and not causing toxicity. Additionally, being vigilant for signs of Stevens-Johnson syndrome, a severe skin reaction associated with Phenytoin use, is crucial for early detection and intervention. Therefore, monitoring behavior, therapeutic blood levels, and for signs of Stevens-Johnson syndrome are all essential when administering Phenytoin.
