1. A client in the post-anesthesia recovery unit received a nondepolarizing neuromuscular blocking agent and has muscle weakness. The nurse should anticipate a prescription for which of the following medications?

Correct answer: A

Rationale: Neostigmine is a cholinesterase inhibitor commonly used to reverse the effects of nondepolarizing neuromuscular blockers, such as the one the client received. It works by inhibiting the breakdown of acetylcholine, thereby enhancing neuromuscular transmission and reversing muscle weakness caused by the neuromuscular blocking agent.

2. When educating a client starting a new prescription for simvastatin, which instruction should the nurse provide?

Correct answer: B

Rationale: The correct instruction for a client starting simvastatin is to report any muscle pain immediately because it could be indicative of rhabdomyolysis, a serious side effect of the medication. This prompt reporting can help prevent further complications and ensure timely medical intervention. Choice A is incorrect because simvastatin can be taken at any time of the day. Choice C is generally true for many medications, but there is no specific interaction between grapefruit juice and simvastatin. Choice D is also incorrect as there is no specific recommendation to take simvastatin at bedtime.

3. When a client is discharged with nitroglycerin (Nitrostat), what should the nurse include in client education?

Correct answer: B

Rationale: The correct answer instructs the client on the appropriate use of nitroglycerin. Nitroglycerin is used to relieve chest pain or angina. If the chest pain does not subside after taking one tablet, the client should take a maximum of three tablets at 5-minute intervals. If the pain persists after three tablets, it could indicate a heart attack, and emergency medical help should be sought. This education is crucial to ensure the client knows when to seek immediate medical attention.

4. What classification of drug is Penicillin?

Correct answer: C

Rationale: Penicillin is classified as an antibacterial drug, specifically used to treat bacterial infections. It works by inhibiting the growth of bacteria, making it an effective treatment for various bacterial infections. Choices A, B, and D are incorrect as Penicillin does not belong to these drug classifications. Penicillin does not have any direct effect on heart rhythm (antiarrhythmic), does not treat seizures (anticonvulsant), and is not used to stabilize mood (mood stabilizer).

5. A healthcare professional is administering a Dopamine infusion at a low dose to a client with severe heart failure. Which of the following findings is an expected effect of this medication?

Correct answer: B

Rationale: Dopamine, when administered at a low dose, is expected to increase myocardial contractility by stimulating beta1 receptors. This positive inotropic effect leads to an increase in cardiac output. Therefore, the correct answer is increased myocardial contractility, as it is a desired effect of administering dopamine to a client with severe heart failure.
