Correct Answer: C

Rationale: Bethanechol is a muscarinic agonist that stimulates muscarinic receptors. Activation of muscarinic receptors can lead to excessive perspiration (diaphoresis) due to increased cholinergic activity, affecting sweat glands. Dry mouth, hypertension, and fecal impaction are not typically associated with muscarinic stimulation.

Correct Answer: B

Rationale: In a situation where a client presents with Benzodiazepine toxicity, the priority action for the nurse is to assess the client. By identifying the client's level of orientation, the nurse can gather crucial information about the client's mental status, which is essential for determining the appropriate care and interventions needed. Administering flumazenil, infusing IV fluids, or preparing for gastric lavage may be necessary interventions but should follow a thorough assessment of the client's condition.

Correct Answer: C

Rationale: The correct answer is C: Sedation. Dextromethorphan can cause sedation, so the client should be advised to avoid activities that require alertness. Diarrhea, anxiety, and palpitations are not commonly associated adverse effects of Dextromethorphan.

Correct Answer: B

Rationale: The nurse should monitor the client for hypertension as a common adverse effect of epoetin alfa, which stimulates red blood cell production and can lead to increased blood pressure.

Correct Answer: D

Rationale: Enoxaparin is a medication that should be administered as a subcutaneous injection in the abdomen to prevent bleeding complications. Massaging the injection site after administration should be avoided to reduce the risk of local irritation or bleeding. Rotating injection sites between the arms and thighs is a good practice for some medications but not recommended for Enoxaparin, which should be consistently given in the abdomen for optimal absorption and to avoid complications.
