1. What is the homeostatic cellular transport mechanism that moves water from a hypotonic to a hypertonic fluid space?

• A. Filtration
• B. Diffusion
• C. Osmosis
• D. Active transport

Correct answer: C

Rationale: The correct answer is C: Osmosis. Osmosis is the homeostatic cellular transport mechanism that moves water from a hypotonic to a hypertonic fluid space to maintain cellular balance. In osmosis, water moves across a semi-permeable membrane from an area of low solute concentration (hypotonic) to an area of high solute concentration (hypertonic). This process helps regulate the water content inside cells. Choices A, B, and D are incorrect. Filtration involves the movement of solutes and solvents through a membrane due to a pressure difference, diffusion is the movement of solutes from an area of high concentration to low concentration, and active transport requires energy to move substances against their concentration gradient.

2. The healthcare provider plans to assess a newborn and check the infant's Moro reflex. What is the healthcare provider evaluating?

• A. Neurological integrity
• B. Renal functioning
• C. Thermoregulation
• D. Respiratory adequacy

Correct answer: A

Rationale: The Moro reflex is an instinctive response observed in newborns, indicating their neurological integrity. This reflex is evaluated by eliciting a startle response in the infant, involving the sudden extension and abduction of the limbs, followed by their retraction. This assessment helps in determining the proper functioning of the infant's nervous system and brain. Choices B, C, and D are incorrect as they do not relate to the evaluation of the Moro reflex. Renal functioning pertains to kidney function, thermoregulation refers to temperature control, and respiratory adequacy involves assessing breathing and oxygenation levels, none of which are evaluated through the Moro reflex.

3. A client with chronic kidney disease (CKD) is receiving erythropoietin therapy. What is the primary purpose of this medication?

• A. To lower blood pressure
• B. To improve appetite
• C. To increase red blood cell production
• D. To reduce fluid retention

Correct answer: C

Rationale: The correct answer is C: 'To increase red blood cell production.' Erythropoietin stimulates the production of red blood cells to treat anemia associated with CKD. Choices A, B, and D are incorrect because erythropoietin therapy is primarily used to address anemia by increasing the production of red blood cells rather than lowering blood pressure, improving appetite, or reducing fluid retention.

4. The wife is observed shaving her husband's beard with a safety razor. What should the nurse do?

• A. Advise the wife to shave against the hair growth
• B. Teach the wife to keep the skin loose to avoid cuts
• C. Encourage the wife to continue shaving her husband
• D. Demonstrate the correct procedure to the wife

Correct answer: C

Rationale: In this situation, the nurse should encourage the wife to continue shaving her husband. The rationale behind this is that the wife is already performing the task, so abrupt interference may lead to potential harm or emotional distress. It is crucial for the nurse to carefully observe the situation and assess for any safety concerns. While teaching proper techniques (Choice B) is important, it can be addressed later in a non-critical manner to prevent skin irritation and injury. Advising to shave against the hair growth (Choice A) may cause skin irritation and cuts. Although demonstrating the correct procedure (Choice D) may be helpful, it is essential to consider the current dynamics and respect the wife's autonomy in caring for her husband.

5. A client is admitted to the hospital with second and third degree burns to the face and neck. How should the nurse best position the client to maximize function of the neck and face and prevent contracture?

• A. The neck extended backward using a rolled towel behind the neck
• B. Prone position using pillows to support both arms outward from the torso
• C. Side-lying position using pillows to support the abdomen and back
• D. The neck forward using pillows under the head and sandbags on both sides

Correct answer: D

Rationale: After sustaining burns to the face and neck, positioning is crucial to maintain functional posture, reduce pain, and prevent contractures. Placing the neck forward using pillows under the head and sandbags on both sides is the best option in this scenario. This position helps prevent neck and facial contractures, allowing for optimal function and healing. Choices A, B, and C do not adequately address the specific needs of a client with burns to the face and neck. Choice A could potentially exacerbate neck contractures, Choice B focuses on arm support rather than neck and face positioning, and Choice C does not directly address the needs of the burned face and neck, making them less effective in preventing contractures in these critical areas.
