For a rectal examination, the patient can be directed to assume which of the following positions?

Correct Answer: B

Rationale: The correct position for a rectal examination is the Sims position, where the patient lies on their left side with the upper knee flexed. This position allows for easy access and visualization of the rectal area for examination.

Correct Answer: A

Rationale: The symptoms of fatigue, muscle cramping, and muscle weakness in a patient after starting furosemide therapy are indicative of hypokalemia. Furosemide is a loop diuretic that can lead to potassium depletion, causing hypokalemia. Hypokalemia can manifest with muscle weakness, cramps, and fatigue due to alterations in neuromuscular function and decreased ATP production.

Correct Answer: C

Rationale: In this scenario, the new head nurse should discuss the problem with her supervisor. This is the most appropriate action as the supervisor is in a position to address staffing concerns effectively and make necessary changes. Complaining to fellow nurses may not lead to a solution, waiting may exacerbate the issue, and demanding staff rotation without proper discussion is not a collaborative approach to resolving the problem.

Correct Answer: C

Rationale: Immobility, diaphoresis, and avoidance of deep breathing or coughing are common signs of pain.

Correct Answer: A

Rationale: The nurse's responsibility in this scenario is to instruct the patient about the diagnostic test ordered by the physician. This includes explaining the purpose of the test, any necessary preparations, and what to expect. The nurse is not responsible for writing the order, as this is the physician's role. Additionally, providing breakfast is not directly related to the platelet count test. Therefore, the correct answer is A, which aligns with the nurse's role in educating and supporting the patient regarding the test.

Correct Answer: B

Rationale: Vitamin C requirements are increased during infancy, childhood, and pregnancy due to growth and development. However, during young adulthood, the body generally requires a consistent amount of Vitamin C as it is not undergoing rapid growth or physiological changes that necessitate an increase in Vitamin C intake.

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.

Correct Answer: D

Rationale: A patient being kept off food and fluids before surgery can lead to dehydration. Dehydration can cause a slight increase in body temperature, which could explain the elevated oral temperature reading of 99.8°F (37.7°C) in this scenario. Infections are more likely to cause higher fevers, hypothermia would present with a lower temperature, and anxiety typically does not directly affect body temperature in this manner.

Correct Answer: A

Rationale: Leukopenia, characterized by low white blood cell count, significantly reduces the body's ability to fight infections. Patients with leukopenia are at a higher risk of contracting infections due to compromised immune defenses.
