1. Which physiologic mechanism best describes the function of the sodium-potassium pump?

• A. active transport
• B. diffusion
• C. filtration
• D. osmosis

Correct answer: A

Rationale: Active transport is the correct answer as it accurately describes the process involved in the sodium-potassium pump. The pump utilizes energy to move ions against their concentration gradient, maintaining cellular concentrations. Diffusion (choice B) is a passive process where substances move from an area of higher concentration to lower concentration. Filtration (choice C) involves the movement of solutes based on pressure gradients. Osmosis (choice D) is the movement of water across a semipermeable membrane.

2. A 70-year-old male who is recovering from a stroke exhibits signs of unilateral neglect. Which behavior is suggestive of unilateral neglect?

• A. The client is observed shaving only one side of his face.
• B. The client is unable to distinguish between two tactile stimuli presented simultaneously.
• C. The client is unable to complete a range of vision without turning his head side to side.
• D. The client is unable to carry out cognitive and motor activity at the same time.

Correct answer: A

Rationale: Unilateral neglect is a condition where a person ignores one side of their body. In this case, the behavior of shaving only one side of the face indicates neglect of the other side. This behavior is suggestive of unilateral neglect as the individual is failing to attend to one side of their body. Choices B, C, and D are not associated with unilateral neglect. Choice B refers to tactile agnosia, a condition where a person cannot recognize objects by touch, not related to ignoring one side of the body. Choice C describes a visual field cut, which is a different visual deficit. Choice D relates to dual-task interference, not specific to ignoring one side of the body.

3. A mother of a newborn notices a nurse placing liquid in her baby's eyes. Which of the following is an inaccurate statement about the need for eyedrops following birth?

• A. Eyedrops following birth help reduce the risk of eye infection.
• B. Eyedrops are required by law.
• C. Eyedrops will keep the eye moist.
• D. Eyedrops are required by law every 6 hours following birth.

Correct answer: D

Rationale: The correct answer is 'Eyedrops are required by law every 6 hours following birth.' This statement is inaccurate because while laws do require the placement of eyedrops, physicians indicate a specific timeframe for their administration. Choice A is correct because eyedrops following birth do help reduce the risk of eye infection by preventing ophthalmia neonatorum. Choice B is incorrect as it implies that eyedrops are mandated solely by law, without considering medical reasons. Choice C is accurate as eyedrops do help keep the eye moist, preventing dryness and discomfort.

4. A 14-year-old boy has been admitted to a mental health unit for observation and treatment. The boy becomes agitated and starts yelling at nursing staff members. What should the nurse's first response be?

• A. Create an atmosphere of seclusion for the boy according to procedures.
• B. Remove other patients from the area for added safety.
• C. Ask the patient, "What is making you mad?"?
• D. Ask the patient, "Why are you behaving this way? Have you thought about what may help you calm down?"?

Correct answer: A

Rationale: In a situation where a patient is agitated and yelling, the first response should be to create an atmosphere of seclusion for the safety of the patient and others. Seclusion is a standard procedure to help manage aggressive behaviors and prevent harm. Options B, C, and D are not appropriate in this scenario. Removing other patients may not address the immediate safety concern, asking the patient what is making them mad can escalate the situation, and questioning why the patient is behaving that way may not help in managing the current agitation. Therefore, seclusion is the recommended course of action in this scenario to ensure the safety and well-being of all involved.

5. Which of the following can certain foods like broccoli, oranges, dark greens, and dark yellow vegetables help improve?

• A. Vitamin intake
• B. Body functions
• C. Defense mechanisms
• D. Disease cure

Correct answer: C

Rationale: Certain foods like broccoli, oranges, dark greens, and dark yellow vegetables can help improve defense mechanisms by enhancing the immune system and overall health. While these foods can boost defense mechanisms, they are not a cure for diseases, do not balance body functions, and are not intended to solely supplement vitamin intake, which may be necessary in some cases. Therefore, the correct answer is defense mechanisms as these foods strengthen the body's ability to fight off illnesses and maintain health.
