1. When administering enoxaparin (Lovenox) to a client, what is the most important lab value to monitor?

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

Correct answer: A

Rationale: The correct answer is A: Platelet count. When administering enoxaparin (Lovenox), it is crucial to monitor the platelet count because enoxaparin can cause a rare but serious side effect known as heparin-induced thrombocytopenia, which is a decrease in platelet count that can lead to increased risk of bleeding. Monitoring the platelet count allows for early detection of this potential complication. Choices B, C, and D are incorrect because aPTT, Hemoglobin, and INR are not the most important lab values to monitor specifically when administering enoxaparin.

2. Which condition is caused by a bacterium that primarily affects the lungs but can spread to other parts of the body?

• A. Tuberculosis
• B. Pneumonia
• C. Legionnaires' disease
• D. Histoplasmosis

Correct answer: A

Rationale: The correct answer is A, Tuberculosis. Tuberculosis is an infectious disease caused by Mycobacterium tuberculosis, primarily affecting the lungs but can spread to other organs. Choice B, Pneumonia, is an infection that inflames the air sacs in one or both lungs. Choice C, Legionnaires' disease, is a severe form of pneumonia caused by the Legionella bacteria. Choice D, Histoplasmosis, is a fungal infection caused by inhaling spores of the Histoplasma capsulatum fungus.

3. Which valve opens during ventricular systole and closes during ventricular diastole?

• A. Aortic valve
• B. Pulmonary valve
• C. Mitral valve
• D. Tricuspid valve

Correct answer: B

Rationale: The correct answer is B: Pulmonary valve. The pulmonary valve opens during ventricular systole to allow blood to flow from the right ventricle into the pulmonary artery. The aortic valve opens during ventricular systole to allow blood to flow from the left ventricle into the aorta. The mitral valve and tricuspid valve are atrioventricular valves that open during ventricular diastole to allow blood to flow from the atria into the ventricles.

4. What test measures the pressure inside the arteries as the heart pumps blood?

• A. Blood pressure test
• B. Pulse oximetry
• C. Echocardiogram
• D. Spirometry

Correct answer: A

Rationale: The correct answer is A) Blood pressure test. A blood pressure test is specifically designed to measure the pressure inside the arteries as the heart pumps blood. This test is crucial in providing information about cardiovascular health by determining the force of blood against the artery walls. Choice B, Pulse oximetry, measures oxygen saturation in the blood, not blood pressure. Choice C, Echocardiogram, is an ultrasound test that evaluates the structure and function of the heart, not specifically blood pressure. Choice D, Spirometry, is a test used to assess lung function, not blood pressure.

5. The client is receiving digoxin and has a potassium level of 2.8 mEq/L. What is the nurse’s priority action?

• A. Hold the digoxin and notify the healthcare provider.
• B. Increase the dose of digoxin.
• C. Continue the current dose of digoxin.
• D. Administer potassium supplements.

Correct answer: A

Rationale: The correct answer is to hold the digoxin and notify the healthcare provider. A potassium level of 2.8 mEq/L indicates hypokalemia, which can increase the risk of digoxin toxicity. Holding the medication and informing the healthcare provider is crucial to prevent adverse effects. Choice B is incorrect because increasing the dose of digoxin would further raise the risk of toxicity. Choice C is incorrect as continuing the current dose could exacerbate the toxicity risk. Choice D is incorrect because administering potassium supplements alone is not sufficient to address the potential digoxin toxicity; the first step should be to hold the digoxin and seek further guidance.
