Correct Answer: B

Rationale: Verifying the client's blood type and Rh factor is crucial before administering blood products to ensure compatibility and prevent adverse reactions. Option A is incorrect because PRBCs are typically infused over a specific time frame based on hospital policy and client condition, not necessarily over 8 hours. Option C is incorrect as PRBCs are usually administered through a larger gauge catheter to prevent hemolysis. Option D is incorrect because PRBCs are typically administered with normal saline and not lactated Ringer's solution.

Correct Answer: C

Rationale: The correct answer is C. Clients taking clopidogrel should take the medication with a full glass of water to prevent gastrointestinal irritation. Choice A is incorrect because there is no specific recommendation to avoid foods high in potassium with clopidogrel. Choice B is unrelated to the medication's administration. Choice D is a duplication of choice C, providing no additional information.

Correct Answer: C

Rationale: In this scenario, the FHR baseline of 100/min for the past 15 minutes indicates fetal bradycardia, which can be caused by maternal hypoglycemia. Maternal hypoglycemia can lead to decreased oxygen supply to the fetus, resulting in fetal bradycardia. Maternal fever (Choice A) typically presents with tachycardia in the fetus rather than bradycardia. Fetal anemia (Choice B) is more likely to manifest as tachycardia due to compensation for decreased oxygen delivery. Chorioamnionitis (Choice D) may lead to fetal tachycardia as a sign of fetal distress, not bradycardia.

Correct Answer: B

Rationale: The correct answer is B: Serotonin syndrome. Serotonin syndrome can occur due to the interaction between citalopram, an SSRI, and St. John's Wort, an herbal supplement. Symptoms of serotonin syndrome include confusion, agitation, rapid heart rate, high blood pressure, dilated pupils, loss of muscle coordination, and sweating. Choices A, C, and D are incorrect as they are not typically associated with the interaction between citalopram and St. John's Wort. Tardive dyskinesia is a movement disorder associated with long-term use of certain medications, pseudoparkinsonism is a side effect of certain antipsychotic medications, and acute dystonia is a movement disorder caused by certain medications like antipsychotics.

Correct Answer: B

Rationale: The correct action for the nurse to take is to assess the client's lung sounds before administering IV fluids. This is crucial to identify any signs of fluid overload, such as crackles or wheezes. Administering the solution slowly over 24 hours (choice A) is not appropriate for an IV bolus, which is a rapid infusion. Changing the IV tubing every 12 hours (choice C) is a standard practice for preventing infection but is not directly related to administering an IV bolus. Flushing the IV line with heparin every 4 hours (choice D) is a maintenance practice to prevent clot formation in the line, not specifically related to administering an IV bolus.
