1. 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.

2. The healthcare provider is preparing to administer an intramuscular injection to an adult client. Which site is the preferred location for this injection?

• A. Deltoid muscle.
• B. Vastus lateralis muscle.
• C. Ventrogluteal muscle.
• D. Dorsogluteal muscle.

Correct answer: C

Rationale: The ventrogluteal site is preferred for intramuscular injections in adults due to its muscle mass and lower risk of nerve injury. The deltoid muscle is more commonly used for vaccines in adults, the vastus lateralis muscle is preferred in infants and young children, and the dorsogluteal muscle is associated with a higher risk of nerve injury and is no longer recommended for intramuscular injections.

3. A client is admitted with diabetic ketoacidosis. What is the most critical treatment to initiate?

• A. Administer sodium bicarbonate IV
• B. Start an insulin drip
• C. Monitor glucose and ketone levels
• D. Provide oral hydration

Correct answer: B

Rationale: In the case of diabetic ketoacidosis, the most critical treatment to initiate is starting an insulin drip. Insulin therapy is crucial for reducing blood glucose levels by promoting glucose uptake in cells and inhibiting the production of ketones. Administering sodium bicarbonate IV is generally not recommended as it may lower the pH further and potentially worsen the condition. While monitoring glucose and ketone levels is important for assessing the response to treatment, initiating insulin therapy takes precedence. Providing oral hydration alone is insufficient to manage the metabolic derangements seen in diabetic ketoacidosis.

4. The nurse is caring for a client with an indwelling urinary catheter. What is the most important action to prevent catheter-associated urinary tract infections (CAUTI)?

• A. Perform hand hygiene before and after handling the catheter
• B. Change the catheter every 72 hours
• C. Apply antibiotic ointment at the insertion site
• D. Irrigate the catheter daily

Correct answer: A

Rationale: Performing hand hygiene before and after handling the catheter is crucial in preventing catheter-associated urinary tract infections (CAUTI). This practice helps minimize the risk of introducing harmful microorganisms into the urinary tract. Changing the catheter every 72 hours is not recommended unless clinically indicated as it can increase the risk of infection. Applying antibiotic ointment at the insertion site is not a standard practice and may contribute to antibiotic resistance. Irrigating the catheter daily is unnecessary and can introduce pathogens into the urinary tract, increasing the risk of infection.

5. In a community health setting, which individual is at highest risk for contracting an HIV infection?

• A. 17-year-old who is sexually active with numerous partners
• B. 34-year-old homosexual in a monogamous relationship
• C. 30-year-old cocaine user who inhales and smokes drugs
• D. 45-year-old who has received two blood transfusions in the past 6 months

Correct answer: C

Rationale: The correct answer is C. Substance abuse, particularly using shared inhalation equipment like needles and pipes for drug inhalation, significantly increases the risk of contracting HIV. Choice A, the 17-year-old with multiple sexual partners, poses a risk of HIV transmission through sexual contact, but it is lower compared to the direct risk associated with sharing drug paraphernalia. Choice B, the 34-year-old homosexual in a monogamous relationship, is at lower risk since being in a monogamous relationship reduces exposure to HIV. Choice D, the 45-year-old who received blood transfusions, is also at lower risk as blood transfusions are now screened for HIV, decreasing the likelihood of transmission through this route.
