A nurse is reviewing the medical history of a client who has a prescription for atenolol 40 mg daily. The nurse knows which of the following findings is a contraindication to the new medication?
The client has a history of migraine headaches.
The client has a history of bronchial asthma.
The client has a history of hypothyroidism.
The client has a history of hypertension.
The Correct Answer is B
Rationale:
A. A history of migraine headaches is not a contraindication to atenolol use.
B. Atenolol is a beta-blocker, and its use is contraindicated in clients with bronchial asthma or a history of severe bronchospastic disease due to the risk of exacerbating bronchospasm.
C. A history of hypothyroidism is not a contraindication to atenolol use.
D. A history of hypertension is an indication for atenolol use, not a contraindication.

Correct Answer is C
Explanation
Rationale:
A. Heparin and warfarin do not work to lower blood pressure. Their primary action is to prevent blood clots, not to affect blood pressure.
B. While heparin can help prevent the extension of existing blood clots, it does not typically dissolve clots. Warfarin is used for long-term anticoagulation and works by inhibiting the synthesis of clotting factors.
C. Heparin is often used initially to rapidly anticoagulate a patient while waiting for the therapeutic effects of warfarin to take effect. Warfarin is then used long-term to prevent future clots from forming.
D. Heparin and warfarin are often given together initially, especially in certain clinical situations such as acute deep vein thrombosis or pulmonary embolism, to achieve rapid anticoagulation while waiting for the therapeutic effects of warfarin. However, careful monitoring is required to minimize the risk of hemorrhage.
Correct Answer is A
Explanation
Rationale:
A. Captopril, an angiotensin-converting enzyme (ACE) inhibitor, commonly causes a dry cough as a side effect due to the accumulation of bradykinin.
B. Captopril typically does not cause drowsiness as a side effect.
C. Captopril may cause a decrease in heart rate as a result of its vasodilatory effects, but this is not a primary therapeutic effect of the medication.
D. Captopril primarily affects blood pressure and heart function but does not directly lower LDL cholesterol levels.
