Adult Health 2 Exam 1

1. What is the primary function of neutrophils?

Correct answer: C

Rationale: The correct answer is C: Phagocytotic action. Neutrophils are key components of the immune system, primarily involved in the phagocytosis of bacteria and other pathogens. Choice A, Heparin secretion, is incorrect as heparin is primarily secreted by mast cells and basophils. Choice B, Transport oxygen, is incorrect as this is mainly the function of red blood cells. Choice D, Antibody formation, is incorrect as antibody production is primarily carried out by B lymphocytes.

2. A client with a history of atrial fibrillation is prescribed warfarin. Which lab value should the nurse monitor to assess the effectiveness of this medication?

Correct answer: D

Rationale: The correct answer is D, INR (International Normalized Ratio). The INR is used to monitor the effectiveness of warfarin therapy. Warfarin is an anticoagulant medication commonly prescribed for conditions like atrial fibrillation. Monitoring the INR helps healthcare providers ensure that the blood is clotting within a therapeutic range. Hemoglobin (Choice A), white blood cell count (Choice B), and platelet count (Choice C) are not directly related to monitoring the effectiveness of warfarin therapy in this context.

3. A client with a diagnosis of chronic heart failure is prescribed digoxin. What is the most important assessment before administering this medication?

Correct answer: B

Rationale: The correct answer is to assess the heart rate before administering digoxin. Digoxin can lead to bradycardia, making it crucial to evaluate the heart rate to prevent potential complications. Checking blood pressure (Choice A) is important but not as critical as assessing the heart rate in this context. Monitoring respiratory rate (Choice C) and measuring oxygen saturation (Choice D) are not the most crucial assessments before administering digoxin, as the primary concern with this medication is its impact on heart rate.

4. A client with hypothyroidism is being treated with levothyroxine (Synthroid). What is the most important information for the nurse to provide to the client?

Correct answer: B

Rationale: The most important information for the nurse to provide to a client with hypothyroidism being treated with levothyroxine is to monitor for signs of hyperthyroidism. Too much levothyroxine can lead to symptoms of hyperthyroidism, indicating an overdose. Choice A is incorrect as levothyroxine is usually taken on an empty stomach to ensure optimal absorption. Choice C is inaccurate as it may take weeks to months to see the full effects of levothyroxine therapy due to the need for dosage adjustments. Choice D is unrelated to levothyroxine therapy and is not a crucial concern for this specific medication.

5. Before a client undergoes a Magnetic Resonance Imaging (MRI) scan with contrast, what should the nurse assess?

Correct answer: A

Rationale: Before an MRI scan with contrast, the nurse should assess if the client has any metal implants. Metal implants can interfere with the magnetic field of the MRI, which can pose a risk to the client's safety and compromise the quality of the scan. Assessing for allergies to iodine or shellfish (Choice B) is important for contrast agents but not specific to metal implants. Claustrophobia assessment (Choice C) is relevant for MRI scans due to the confined space but not specific to metal implants. Past procedures (Choice D) are important for comparison but not directly related to the risks associated with metal implants during an MRI scan with contrast.
