Correct Answer: A

Rationale: In a Trendelenberg position, used for low blood pressure, the correct action is to lower the head of the bed and raise the foot of the bed. This positioning facilitates the return of blood to the heart and helps increase blood pressure. Option B, raising the head of the bed to 60 to 75 degrees, is incorrect as it is not the Trendelenberg position. Option C, raising the head of the bed to 75 to 90 degrees, is incorrect as it does not align with the Trendelenberg position. Option D, raising the siderails and placing the bed in the high position, is incorrect as it does not address the specific positioning required for the Trendelenberg position.

Correct Answer: A

Rationale: Intermittent fevers are characterized by periods of fever followed by periods of normal body temperature. They alternate between being febrile and afebrile. Continuous fevers show minimal fluctuations over a 24-hour period, while remittent fevers fluctuate significantly but do return to normal body temperature.
Choice A is correct as it accurately describes intermittent fevers.

Choices B and C are incorrect as they do not fully capture the defining characteristic of intermittent fevers, which involve cyclical episodes of fever and normal temperature.
Choice D is incorrect as there is a specific definition for intermittent fevers.

Correct Answer: B

Rationale: The correct answer is 'An overabundance of a particular white blood cell in the peripheral blood.' Basophilia specifically indicates an increased number of basophils in the peripheral blood. It can be observed in conditions like leukemia and certain allergic reactions.
Choice A is incorrect as it describes something unrelated to basophilia.
Choice C is incorrect as it suggests a decrease in basophils, which is opposite to the actual meaning of basophilia.
Choice D is also incorrect as basophilia does have a defined medical significance.

Correct Answer: D

Rationale: The Jack Knife position is the most useful for proctologic exams as it allows the patient to lie face down while keeping the buttocks elevated, providing optimal access for the examination. The Trendelenburg position, characterized by the body being laid flat with the feet higher than the head, is not suitable for proctologic exams. Semi-Fowler's and Full Fowler's positions are typically utilized for respiratory or cardiovascular conditions and are not ideal for proctologic examinations due to their lack of optimal access to the perianal area.

Correct Answer: B

Rationale: The correct answer is 'lateral.' The Sims' position is characterized by the patient lying on their side with the upper knee flexed and the upper arm positioned in front of the body. This is similar to the lateral position where the patient is also lying on their side. The prone position (choice
A) is when the patient lies face down, the supine position (choice
C) is when the patient lies face up, and Fowler's position (choice
D) is a seated position with the head of the bed elevated at a 45-90 degree angle.
Therefore, the lateral position is the most similar to the Sims' position as both involve the patient lying on their side.
