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. A client with a diagnosis of chronic heart failure is receiving digoxin. What is the most important assessment before administering this medication?

• A. Check blood pressure.
• B. Assess heart rate.
• C. Monitor respiratory rate.
• D. Measure oxygen saturation.

Correct answer: B

Rationale: The correct answer is to assess the heart rate. Before administering digoxin, it is essential to evaluate the heart rate as digoxin can cause bradycardia. While checking blood pressure, monitoring respiratory rate, and measuring oxygen saturation are important assessments in the care of a client with chronic heart failure, assessing the heart rate is particularly critical due to the medication's potential impact on heart rhythm.

3. What is the most important aspect of colostomy care to teach the client?

• A. Change the colostomy bag only when necessary
• B. Eat a low-residue diet
• C. Assess the stoma for color and swelling
• D. Irrigate the colostomy only if advised by a healthcare provider

Correct answer: C

Rationale: The most important aspect of colostomy care to teach the client is to assess the stoma for color and swelling. This is crucial as it ensures early detection of complications such as ischemia or infection. Changing the colostomy bag only when necessary is more appropriate than doing it daily, as it prevents unnecessary changes that may irritate the skin. While eating a low-residue diet is beneficial, it is not the most crucial aspect to teach. Irrigating the colostomy should only be done if advised by a healthcare provider, as it is not a routine procedure for all clients with a colostomy.

4. 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.

5. 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.
