1. The client is on enoxaparin (Lovenox) for DVT prophylaxis. What is the most important lab value to monitor?

• A. Platelet count
• B. PT/INR
• C. aPTT
• D. Hemoglobin

Correct answer: A

Rationale: The correct answer is A: Platelet count. When a client is on enoxaparin (Lovenox), monitoring the platelet count is crucial as enoxaparin can lead to a rare but serious side effect known as heparin-induced thrombocytopenia (HIT), causing a decrease in platelet count. Monitoring the platelet count helps detect this adverse reaction early. Choices B, C, and D are incorrect because enoxaparin therapy does not directly affect PT/INR, aPTT, or hemoglobin levels.

2. Which condition is characterized by chronic inflammation of the airways resulting in excess mucus production, leading to frequent coughing and breathing difficulties?

• A. Chronic bronchitis
• B. Asthma
• C. Pneumonia
• D. COPD

Correct answer: A

Rationale: The correct answer is A, Chronic bronchitis. Chronic bronchitis involves long-term inflammation of the bronchi, leading to excessive mucus production, frequent coughing, and breathing difficulties. Asthma (B) is characterized by reversible airway obstruction and bronchospasms. Pneumonia (C) is an infection of the lungs caused by bacteria, viruses, or fungi. COPD (D) is a term used to describe chronic lung diseases that cause airflow blockage and breathing-related problems.

3. What term describes a condition where a person experiences difficulty breathing when lying flat and requires multiple pillows to sleep comfortably?

• A. Orthopnea
• B. Dyspnea
• C. Tachypnea
• D. Bradypnea

Correct answer: A

Rationale: The correct answer is A, Orthopnea. Orthopnea is a condition where a person finds it hard to breathe while lying flat and needs to use multiple pillows to sleep comfortably. This position helps relieve the discomfort by allowing better lung expansion. Choice B, Dyspnea, refers to difficulty breathing in general, not specifically related to lying flat. Choice C, Tachypnea, is rapid breathing and is not directly related to difficulty breathing while lying down. Choice D, Bradypnea, is slow breathing and does not describe the condition of having trouble breathing when lying flat.

4. Which heart chamber receives oxygenated blood from the lungs and pumps it to the rest of the body?

• A. Left atrium
• B. Right atrium
• C. Left ventricle
• D. Right ventricle

Correct answer: C

Rationale: The correct answer is the left ventricle. It receives oxygenated blood from the left atrium and pumps it to the rest of the body through the aorta. The left atrium receives oxygenated blood from the lungs, the right atrium receives deoxygenated blood from the body, and the right ventricle pumps deoxygenated blood to the lungs.

5. The client is on enalapril (Vasotec) for hypertension. What side effect is most commonly associated with this medication?

• A. Dry cough
• B. Hypotension
• C. Hyperkalemia
• D. Headache

Correct answer: A

Rationale: The correct answer is A: Dry cough. A dry cough is a common side effect of ACE inhibitors like enalapril. ACE inhibitors can cause the accumulation of bradykinin, leading to irritation of the respiratory tract and resulting in a persistent dry cough. Hypotension (choice B) is a possible side effect of ACE inhibitors but is less common than a dry cough. Hyperkalemia (choice C) is another side effect of ACE inhibitors, but it is not the most commonly associated one. Headache (choice D) is not a common side effect of enalapril compared to a dry cough. Therefore, the most commonly associated side effect with enalapril is a dry cough.
