Correct Answer: A

Rationale: After reconstitution, the concentration of cefazolin solution is calculated by dividing the total amount of drug (600 mg) by the total volume after reconstitution (2.5 mL). This gives 600 mg / 2.5 mL = 240 mg/mL. However, the question asks for the concentration in each milliliter of solution after reconstitution, so we need to consider the final volume of 2.5 mL. Therefore, 240 mg/mL * 2.5 mL = 600 mg, which means each milliliter contains 240 mg of cefazolin. Therefore, after reconstitution, there are 400 mg of cefazolin in each milliliter of solution. Choices B, C, and D are incorrect as they do not accurately reflect the concentration after reconstitution.

Correct Answer: C

Rationale: The most important information the nurse should provide to a client prescribed an SSRI for depression is to report any thoughts of self-harm immediately. SSRIs can increase suicidal ideation, especially at the beginning of treatment, so it is crucial to monitor for this and take appropriate actions. While it is important to take the medication as prescribed (Choice A), the immediate need for reporting self-harm ideation takes precedence. Avoiding grapefruit juice (Choice B) is a general precaution with certain medications but not as critical in this scenario. Understanding that improvement may take weeks (Choice D) is important for managing treatment expectations, but ensuring the client's safety in the context of suicidal ideation is the top priority.

Correct Answer: B

Rationale: The correct answer is B: 'It ensures clearer imaging by emptying the stomach.' Fasting before an abdominal ultrasound is essential to empty the stomach, allowing for better visualization of the abdominal organs. This improves the quality of the imaging and enhances diagnostic accuracy. Choices A, C, and D are incorrect because reducing intestinal gases, preventing aspiration, and being a standard procedure for surgical interventions are not the primary reasons for fasting before an abdominal ultrasound.

Correct Answer: D

Rationale: The most important instruction the nurse should provide to a client prescribed alendronate (Fosamax) for osteoporosis is to take the medication with a full glass of water. This is crucial to help prevent esophageal irritation. Option A is correct as alendronate should be taken in the morning on an empty stomach. Option C is incorrect because the client should remain upright for at least 30 minutes after taking the medication, not lie down. Option B is incorrect and a duplicate of Option A.
