Correct Answer: A

Rationale: The correct instruction for a client prescribed ferrous sulfate for anemia is to take the medication on an empty stomach. This is because ferrous sulfate is best absorbed in an acidic environment, which is enhanced on an empty stomach. However, if the client experiences gastrointestinal side effects, they can take the medication with food. Choice B, notifying the provider if stool becomes dark green, is correct because dark or black stools are common with iron therapy and not a cause for concern. Choice C, decreasing dietary fiber intake, is incorrect as dietary fiber does not interfere with the absorption of ferrous sulfate. Choice D, taking prescribed antacids at the same time, is incorrect as antacids can decrease the absorption of ferrous sulfate.

Correct Answer: B

Rationale: The correct answer is B: Increased respiratory rate. In pneumonia, the body tries to compensate for the reduced ability to oxygenate the blood by increasing the respiratory rate. This helps to improve oxygen exchange. Bradycardia (Choice A) is not typically associated with pneumonia, as an increased heart rate is more common due to the stress on the body. Decreased temperature (Choice C) is not a typical finding in pneumonia, as infections usually cause a fever. Elevated blood pressure (Choice D) is not a common finding in pneumonia unless there are complications such as sepsis.

Correct Answer: B

Rationale: The correct answer is B: 'Monitor for signs of infection.' After surgery, it is essential for clients to watch for signs of infection, such as increased redness, swelling, or drainage at the incision site. Choice A is incorrect because resuming normal activities immediately after surgery can be harmful. Choice C is incorrect as complete avoidance of physical activity for a month is typically not necessary and can lead to complications like blood clots. Choice D is incorrect as taking pain medications only as needed may not provide adequate pain management post-surgery.

Correct Answer: B

Rationale: The correct answer is B: 'Sit upright for at least 30 minutes after taking it.' Alendronate can cause esophageal irritation and to reduce the risk of this side effect, clients should be instructed to sit upright for at least 30 minutes after administration. Choice A is incorrect as alendronate should be taken on an empty stomach, usually in the morning, at least 30 minutes before the first food, beverage, or medication of the day. Choice C is incorrect because alendronate should not be taken at bedtime, as the client should remain upright for at least 30 minutes after taking it. Choice D is incorrect as antacids can interfere with the absorption of alendronate, so they should not be taken together.

Correct Answer: A

Rationale: The correct answer is to assess blood pressure first before administering nitroglycerin. Nitroglycerin is a vasodilator that can cause a sudden drop in blood pressure, leading to adverse effects such as dizziness or fainting. Assessing blood pressure before administration helps determine if the patient's blood pressure is within the acceptable range for nitroglycerin administration. Heart rate, pain level, and respiratory rate are also important assessments, but blood pressure should take precedence due to the vasodilating effects of nitroglycerin.
