A client at risk for coronary artery disease seeks advice from a nurse. What should the nurse recommend to reduce the risk?

Correct Answer: B

Rationale: The correct recommendation to reduce the risk of coronary artery disease is to exercise for at least 150 minutes per week. Regular exercise is crucial in maintaining cardiovascular health and reducing the chances of developing heart disease. Increasing intake of saturated fats (Choice A) is counterproductive as it can raise cholesterol levels and contribute to arterial plaque formation. Taking iron supplements daily (Choice C) is not directly related to reducing the risk of coronary artery disease. Limiting fruits and vegetables in the diet (Choice D) is also not advisable, as they are essential components of a heart-healthy diet due to their high fiber and nutrient content.

Correct Answer: B

Rationale: The correct answer is B: International normalized ratio (INR). The INR is used to monitor the effectiveness of warfarin therapy. A higher INR indicates a longer time it takes for the blood to clot, which is desirable in patients receiving warfarin to prevent blood clots. Platelet count (Choice A) assesses the number of platelets in the blood and is not directly related to warfarin therapy. Bleeding time (Choice C) evaluates the time it takes for a person to stop bleeding after a standardized wound, but it is not specific to monitoring warfarin effectiveness. Partial thromboplastin time (PTT) (Choice D) is more commonly used to monitor heparin therapy, not warfarin.

Correct Answer: A

Rationale: The correct answer is A: Decreased deep tendon reflexes. Magnesium sulfate toxicity can lead to diminished deep tendon reflexes, respiratory depression, and decreased urine output. Diminished deep tendon reflexes are an early sign of magnesium toxicity and indicate the need to discontinue the infusion. Elevated blood pressure (choice B) is not typically associated with magnesium toxicity. Increased urinary output (choice C) is also not a common finding in magnesium toxicity. Hyperreflexia (choice D) is not consistent with the expected findings of magnesium toxicity, which typically causes decreased reflexes.

Correct Answer: C

Rationale: The correct answer is C. This statement indicates understanding because the client recognizes that they should use the PCA pump when they start to feel pain. Waiting for the pain to become severe is not recommended as it may lead to inadequate pain control. Option B is incorrect because only the client should control the PCA pump to ensure safety and appropriate dosing. Option D is also incorrect as there is no set limit on how often the button can be pressed, as it should be used as needed when pain is felt.

Correct Answer: B

Rationale: The correct answer is B: Oliguria. Oliguria (low urine output) is a sign of decreased cardiac output because the kidneys are not receiving enough blood to produce an adequate amount of urine. Shivering (choice A) is a response to hypothermia or the body's attempt to generate heat. Bradypnea (choice C) refers to abnormally slow breathing rate and is not directly related to cardiac output. Constricted pupils (choice D) are more indicative of conditions affecting the nervous system or medications.

Correct Answer: A

Rationale: The correct answer is A: Drinking grapefruit juice. Grapefruit juice can increase the risk of statin toxicity by interfering with the enzyme that metabolizes statin medications, leading to higher drug levels in the body. This interaction can potentially cause adverse effects. Therefore, patients should be advised to avoid consuming grapefruit juice while taking statins. Choices B, C, and D are incorrect. Consuming high-protein meals, exercising regularly, and taking the medication in the morning are not contraindicated while on statin therapy. In fact, following a healthy diet, engaging in physical activity, and taking the medication at a consistent time each day can be beneficial for patients prescribed statins.

Correct Answer: B

Rationale: Elevating the leg promotes venous return and reduces swelling, which is crucial for clients with DVT. Massaging the affected extremity can dislodge the clot and worsen the condition. Applying cold packs can cause vasoconstriction, potentially increasing the risk of clot formation. Keeping the leg dependent can impede circulation and increase the risk of clot migration.

Correct Answer: C

Rationale: Inviting the patient to share concerns is an example of a culturally sensitive response as it acknowledges the patient's feelings and provides a safe space for them to express their discomfort. This approach shows respect for the patient's cultural beliefs and values by valuing their perspective. Choice A, asking why they feel this way, can be perceived as confrontational and may not encourage open communication. Choice B, explaining that the treatment is standard, dismisses the patient's feelings and does not address their discomfort. Choice D, offering alternative treatments, may be premature without fully understanding the patient's concerns first.

Correct Answer: B

Rationale: The correct answer is to take the medication with a full glass of water. Alendronate should be taken with a full glass of water to prevent esophageal irritation. Additionally, the client should remain upright for 30 minutes after taking it to prevent potential adverse effects. Choice A is incorrect because alendronate should not be taken at bedtime, but rather in the morning on an empty stomach. Choice C is incorrect because alendronate should be taken on an empty stomach, not with food. Choice D is incorrect because the client should remain upright, not lie down, for 30 minutes after taking the medication.
