1. Which intervention is most effective in preventing the spread of infection in a healthcare setting?

• A. Wearing gloves
• B. Using hand sanitizer
• C. Practicing hand hygiene
• D. Disinfecting surfaces

Correct answer: C

Rationale: Practicing hand hygiene is the most effective measure to prevent the spread of infection in healthcare settings. While wearing gloves, using hand sanitizer, and disinfecting surfaces are important infection control measures, they are not as effective as proper hand hygiene. Hand hygiene, including handwashing with soap and water or using alcohol-based hand sanitizers, is crucial in preventing the transmission of pathogens from one person to another, making it the best choice among the options provided. Wearing gloves primarily protects the wearer and is not a substitute for hand hygiene. Using hand sanitizer is helpful but may not be as effective as proper handwashing. Disinfecting surfaces is important but does not address the direct transmission of pathogens through hand contact, which hand hygiene effectively prevents.

2. A client with a history of chronic back pain is prescribed oxycodone for pain management. What is the most important instruction the nurse should provide?

• A. Take the medication with food to reduce stomach upset
• B. Avoid operating heavy machinery while taking this medication
• C. Increase physical activity to enhance pain relief
• D. Report any signs of respiratory depression immediately

Correct answer: D

Rationale: The correct answer is D: 'Report any signs of respiratory depression immediately.' Respiratory depression is a severe side effect of opioids like oxycodone and can be life-threatening. It is crucial for the nurse to instruct the client to report any signs such as slow or shallow breathing, difficulty breathing, or confusion. Choice A is incorrect as taking oxycodone with or without food does not significantly affect its efficacy. Choice B is incorrect because avoiding driving is important due to the potential impairment caused by oxycodone, but reporting respiratory depression is more critical. Choice C is incorrect as increasing physical activity may not always be suitable for individuals with chronic back pain and is not directly related to preventing respiratory depression.

3. A client is receiving dexamethasone (Decadron). What symptoms should the nurse recognize as Cushingoid side effects?

• A. Moon face, slow wound healing, muscle wasting, sodium and water retention
• B. Tachycardia, hypertension, weight loss, heat intolerance, nervousness, restlessness, tremor
• C. Bradycardia, weight gain, cold intolerance, myxedema facies and periorbital edema
• D. Hyperpigmentation, hyponatremia, hyperkalemia, dehydration, hypotension

Correct answer: A

Rationale: Cushingoid side effects are characteristic of excess corticosteroid use, such as dexamethasone. These include moon face (rounding of the face), slow wound healing, muscle wasting, and sodium and water retention. Options B, C, and D describe symptoms that are not typically associated with Cushingoid side effects. Tachycardia, hypertension, weight loss, heat intolerance, nervousness, restlessness, tremor (Option B) are not typical of Cushingoid effects, while bradycardia, weight gain, cold intolerance, myxedema facies, and periorbital edema (Option C) are more indicative of hypothyroidism. Hyperpigmentation, hyponatremia, hyperkalemia, dehydration, and hypotension (Option D) are not classical features of Cushingoid side effects.

4. 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.

5. The nurse is caring for a client with increased intracranial pressure (ICP). Which position should the nurse avoid?

• A. Keeping the head of the bed elevated at 30 degrees
• B. Positioning the client in the prone position
• C. Placing the client in a lateral recumbent position
• D. Elevating the client's legs

Correct answer: B

Rationale: The correct answer is B: Positioning the client in the prone position. Placing the client in the prone position should be avoided in a client with increased intracranial pressure (ICP) as it can further raise ICP. The prone position can hinder venous return and increase pressure within the cranial vault, potentially worsening the client's condition. Keeping the head of the bed elevated at 30 degrees helps promote venous drainage and reduce ICP. Placing the client in a lateral recumbent position can also assist in reducing ICP by optimizing cerebral perfusion. Elevating the client's legs can help improve venous return and maintain adequate cerebral blood flow, making it a suitable positioning intervention for managing increased ICP.
