1. When using a metered-dose inhaler (MDI), which step is most important for ensuring effective medication delivery?

• A. Exhale completely before using the inhaler
• B. Inhale quickly while pressing down on the inhaler
• C. Shake the inhaler for 10 seconds before use
• D. Hold breath for 5 seconds after inhaling

Correct answer: A

Rationale: The correct step to ensure effective medication delivery when using a metered-dose inhaler (MDI) is to exhale completely before using the inhaler. This action helps create more space in the lungs for the medication to reach deeply into the airways. Inhaling quickly while pressing down on the inhaler (Choice B) may cause the medication to impact the throat rather than reaching the lungs. Shaking the inhaler for 10 seconds before use (Choice C) is important to mix the medication but not the most crucial step for effective delivery. While holding the breath for 5 seconds after inhaling (Choice D) can help the medication stay in the lungs momentarily, exhaling completely before inhalation is more critical for optimal drug deposition.

2. The nurse is assessing a client with congestive heart failure who is receiving furosemide (Lasix). Which laboratory value should the nurse monitor closely?

• A. Sodium level
• B. Potassium level
• C. Calcium level
• D. Chloride level

Correct answer: B

Rationale: The correct answer is B: Potassium level. Furosemide is a loop diuretic that can cause potassium loss, leading to hypokalemia. Monitoring the potassium level is crucial to prevent complications such as cardiac arrhythmias. Sodium level (choice A) is not typically affected by furosemide. Calcium level (choice C) and chloride level (choice D) are also not the primary focus of monitoring when a client is on furosemide for heart failure.

3. Which organ lies retroperitoneally?

• A. Kidneys
• B. Testicles
• C. Urinary bladder
• D. Pancreas

Correct answer: A

Rationale: The correct answer is A: Kidneys. The kidneys are located retroperitoneally, behind the peritoneum, providing structural protection and maintaining a stable position within the abdominal cavity. This location helps protect them from external physical trauma. Choices B, C, and D are incorrect because testicles, urinary bladder, and pancreas are not located retroperitoneally. Testicles are located in the scrotum, the urinary bladder is located in the pelvis, and the pancreas is located in the upper abdomen, not retroperitoneally.

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. Based on the Nursing diagnosis of 'Potential for infection related to second and third degree burns,' which intervention has the highest priority?

• A. Application of topical antibacterial cream
• B. Use of careful hand washing technique
• C. Administration of plasma expanders
• D. Limiting visitors to the burned client

Correct answer: B

Rationale: The highest priority intervention in this scenario is B, the use of careful hand washing technique. Proper hand hygiene is essential in preventing infection, especially in individuals with compromised skin integrity like those with burns. By practicing careful hand washing, healthcare providers reduce the risk of introducing harmful pathogens to the burn wound, thus lowering the chances of infections. Choice A, application of topical antibacterial cream, is important but should follow ensuring proper hand hygiene. Choice C, administration of plasma expanders, is not directly associated with preventing burn-related infections. Choice D, limiting visitors, is significant for infection control, but ensuring proper hand hygiene outweighs this intervention in terms of priority.
