1. Which of the following conditions may necessitate fluid restriction?

• A. Fever
• B. Chronic Obstructive Pulmonary Disease
• C. Renal Failure
• D. Dehydration

Correct answer: C

Rationale: Renal failure often necessitates fluid restriction to prevent fluid overload. In renal failure, the kidneys are unable to effectively filter and excrete excess fluids, leading to fluid accumulation in the body. Restricting fluid intake helps manage this condition by preventing further fluid buildup and complications such as edema and electrolyte imbalances.

2. Which chamber of the heart receives oxygenated blood from the lungs?

• A. Left atrium
• B. Right atrium
• C. Left ventricle
• D. Right ventricle

Correct answer: A

Rationale: The correct answer is A, the left atrium. The left atrium receives oxygenated blood from the lungs through the pulmonary veins. This blood is then pumped into the left ventricle before being circulated throughout the body. The right atrium, represented by choice B, actually receives deoxygenated blood from the body through the vena cava. Choices C and D, the left ventricle and right ventricle respectively, are chambers involved in pumping blood out of the heart to the body and lungs, rather than receiving blood from the lungs.

3. After 1 week of hospitalization, Mr. Gray develops hypokalemia. Which of the following is the most significant symptom of his disorder?

• A. Lethargy
• B. Increased pulse rate and blood pressure
• C. Muscle weakness
• D. Muscle irritability

Correct answer: C

Rationale: Muscle weakness is a hallmark symptom of hypokalemia. Hypokalemia refers to low levels of potassium in the blood, which can affect muscle function. The decreased potassium levels can lead to muscle weakness, cramping, and even paralysis. These symptoms can impact various muscle groups in the body, making muscle weakness the most significant symptom to monitor and address in patients with hypokalemia.

4. A healthcare professional is assessing a client following a gunshot wound to the chest. For which of the following findings should the healthcare professional not monitor to detect a pneumothorax?

• A. Tachypnea
• B. Deviation of the trachea
• C. Bradycardia
• D. Pleuritic pain

Correct answer: C

Rationale: Bradycardia, which is a slow heart rate, is not typically associated with a pneumothorax. In a pneumothorax, the presence of air in the pleural space can lead to lung collapse, causing symptoms such as tachypnea (rapid breathing), deviation of the trachea, and pleuritic pain. Monitoring for bradycardia may not be as relevant in this context as it is not a typical indicator of a pneumothorax.

5. When preparing to administer an IM injection that is irritating to the subcutaneous tissue, what is the best action to prevent tracking of the medication?

• A. Use a small gauge needle
• B. Apply ice on the injection site
• C. Administer at a 45° angle
• D. Use the Z-track technique

Correct answer: D

Rationale: The Z-track technique is the best action to prevent tracking of the medication when administering an IM injection that is irritating to the subcutaneous tissue. This technique involves pulling the skin to the side before administering the injection and then releasing the skin after the injection. By doing so, a zig-zag pathway is created, preventing the medication from leaking into the subcutaneous tissue and reducing irritation. Options A, B, and C are incorrect. Using a small gauge needle may not prevent tracking of the medication. Applying ice on the injection site or administering at a 45° angle does not specifically address preventing tracking of the medication in cases where the injection is irritating to the subcutaneous tissue.
