1. Which intervention is most effective in preventing the spread of infection in a healthcare setting?

• A. Wearing gloves
• B. Using hand sanitizer
• C. Practicing hand hygiene
• D. Disinfecting surfaces

Correct answer: C

Rationale: Practicing hand hygiene is the most effective measure to prevent the spread of infection in healthcare settings. While wearing gloves, using hand sanitizer, and disinfecting surfaces are important infection control measures, they are not as effective as proper hand hygiene. Hand hygiene, including handwashing with soap and water or using alcohol-based hand sanitizers, is crucial in preventing the transmission of pathogens from one person to another, making it the best choice among the options provided. Wearing gloves primarily protects the wearer and is not a substitute for hand hygiene. Using hand sanitizer is helpful but may not be as effective as proper handwashing. Disinfecting surfaces is important but does not address the direct transmission of pathogens through hand contact, which hand hygiene effectively prevents.

2. A client with a history of hypertension is prescribed lisinopril. Which potential side effect should the nurse monitor for?

• A. Hypokalemia
• B. Hyperglycemia
• C. Persistent cough
• D. Tachycardia

Correct answer: C

Rationale: The correct answer is C: Persistent cough. Lisinopril is an ACE inhibitor commonly associated with a persistent dry cough as a side effect. This cough is thought to result from increased bradykinin levels. Choices A, B, and D are incorrect. Hypokalemia is not a common side effect of lisinopril; in fact, it may lead to hyperkalemia. Hyperglycemia is not a typical side effect of lisinopril use. Tachycardia is also not a common side effect associated with ACE inhibitors like lisinopril.

3. Which of the following are key parameters that produce blood pressure? (Select ONE that does not apply)

• A. Heart rate
• B. Stroke volume
• C. Peripheral resistance
• D. Neuroendocrine hormones

Correct answer: D

Rationale: Heart rate, stroke volume, and peripheral resistance are indeed key parameters that directly influence blood pressure. Heart rate refers to the number of times the heart beats per minute, affecting how much blood is pumped. Stroke volume is the amount of blood pumped by the heart in one contraction. Peripheral resistance is the resistance of the arteries to blood flow, impacting the pressure needed to push blood through. Neuroendocrine hormones, while they can indirectly influence blood pressure regulation by affecting factors like blood volume and vascular tone, are not direct final parameters that produce blood pressure.

4. What is the primary function of neutrophils?

• A. Heparin secretion
• B. Transport oxygen
• C. Phagocytotic action
• D. Antibody formation

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.

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

• A. Take the medication at bedtime.
• B. Take the medication with food.
• C. Report any symptoms of hyperthyroidism.
• D. Discontinue the medication if you feel well.

Correct answer: C

Rationale: The most important information for the nurse to provide to a client with hypothyroidism being treated with levothyroxine is to report any symptoms of hyperthyroidism. Symptoms of hyperthyroidism, such as palpitations or tremors, may indicate overtreatment or excessive dosing of levothyroxine. Prompt reporting of these symptoms is crucial to prevent serious complications. Choices A and B are not the most critical information related to levothyroxine administration. Instructing the client to take the medication at bedtime or with food can be important for adherence but is not as crucial as monitoring for signs of hyperthyroidism. Choice D is incorrect as discontinuing the medication if feeling well can lead to a relapse of hypothyroidism symptoms.
