Correct Answer: B

Rationale: The correct answer is to rotate injection sites within the same region to prevent tissue damage. By rotating sites, the client can prevent lipodystrophy, which is a condition characterized by the loss or change in body fat at the site of repeated injections. This practice also helps to ensure proper insulin absorption. Storing unopened vials of insulin in the refrigerator (Choice A) is correct, not in the freezer, as freezing can damage the insulin. Administering insulin at a 90-degree angle (Choice C) is more appropriate for subcutaneous injections, while a 45-degree angle is used for intramuscular injections. Massaging the injection site after administering insulin (Choice D) is not recommended as it can affect insulin absorption rates.

Correct Answer: B

Rationale: The correct statement the nurse should include when teaching a client taking clopidogrel is to monitor for signs of infection. Clopidogrel affects platelet levels and can increase the risk of bleeding. Monitoring for signs of infection is crucial because a compromised immune system can make the client more susceptible to infections. Choices A, C, and D are incorrect because clopidogrel is not directly linked to alcohol restrictions, food requirements, or specific water intake instructions.

Correct Answer: D

Rationale: Administering calcium gluconate IV is the correct action when a client displays toxicity from magnesium sulfate. Calcium gluconate is used as the antidote for magnesium sulfate toxicity as it counteracts the effects. Positioning the client supine (Choice A) is not the immediate action needed. Administering dextrose 5% in water (Choice B) is not indicated for magnesium sulfate toxicity. Administering methylergonovine IM (Choice C) is used in postpartum hemorrhage, not for magnesium sulfate toxicity.

Correct Answer: C

Rationale: The correct answer is C. A weight gain of 2.2 kg (5 lb) in 1 week can indicate fluid retention, a serious side effect of fluoxetine that should be reported to the provider. Choices A, B, and D are within normal ranges and are not alarming findings that would require immediate reporting to the provider. A heart rate of 80/min, blood pressure of 130/80 mm Hg, and a temperature of 37.2°C (99°F) are all within normal limits and not typically concerning in a client taking fluoxetine.

Correct Answer: C

Rationale: The correct answer is C: Provide the client with a stool softener. Thrombocytopenia is a condition characterized by a low platelet count, which can lead to an increased risk of bleeding. Providing the client with a stool softener helps prevent constipation, reduces the need for straining during bowel movements, and ultimately decreases the risk of bleeding. Choice A is incorrect as flossing daily does not directly address the issue of bleeding risk associated with thrombocytopenia. Choice B is incorrect as removing fresh flowers from the client's room is more related to the risk of infection rather than bleeding in thrombocytopenia. Choice D is incorrect as avoiding serving raw vegetables does not directly impact the risk of bleeding in clients with thrombocytopenia.
