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 has a prescription for enteric-coated (EC) aspirin 325mg PO daily. The medication drawer contains one 325mg aspirin. What action should the nurse take?
- A. Contact the pharmacy and request the prescribed form of aspirin
- B. Instruct the client about the effects of the medication
- C. Administer the aspirin with a full glass of water or a small snack
- D. Withhold the aspirin until consulting with the healthcare provider
Correct answer: A
Rationale: The correct action for the nurse to take is to contact the pharmacy and request the prescribed form of aspirin. Enteric-coated medications are designed to dissolve in the intestine, not the stomach, to avoid irritation. Therefore, it is essential to ensure the client receives the correct form of aspirin as prescribed. Instructing the client about the effects of the medication (choice B) is not necessary at this point as the issue is related to the form of the aspirin. Administering the aspirin with a full glass of water or a small snack (choice C) is not appropriate as it does not address the need for the correct form of the medication. Withholding the aspirin (choice D) without consulting the healthcare provider is not advisable as it may lead to a delay in the client receiving the necessary medication.
3. A client with a history of hypertension is prescribed hydrochlorothiazide (HCTZ). Which adverse effect should the nurse monitor for?
- A. Hyperkalemia
- B. Hyponatremia
- C. Bradycardia
- D. Hyperglycemia
Correct answer: B
Rationale: The correct answer is 'B. Hyponatremia.' Hydrochlorothiazide can lead to electrolyte imbalances, such as hyponatremia, due to its diuretic effect. This potential adverse effect should be closely monitored in patients taking HCTZ. Choice A, hyperkalemia, is less likely to occur with HCTZ as it tends to cause hypokalemia. Choice C, bradycardia, is not a common adverse effect of HCTZ. Choice D, hyperglycemia, is also less commonly associated with HCTZ use compared to hyponatremia.
4. The nurse is monitoring a client with an IV infusion in the left antecubital fossa. The site is warm, red, and without swelling. What conclusion should the nurse draw from these findings?
- A. The IV fluids are infusing into the subcutaneous tissues
- B. The infusion pump is functioning properly
- C. The insertion date should be verified and the IV discontinued
- D. The site is inflamed and should be reported
Correct answer: B
Rationale: The correct answer is B. Warmth and redness at the IV site without swelling indicate a localized reaction, which is common and does not necessarily indicate infiltration of IV fluids into the subcutaneous tissues. The absence of swelling suggests that the IV is correctly placed. Therefore, the nurse should conclude that the infusion pump is functioning properly. Choice A is incorrect as warmth and redness alone do not indicate subcutaneous infiltration. Choice C is incorrect as discontinuing the IV solely based on warmth and redness without swelling is not necessary. Choice D is incorrect as the absence of swelling signifies a localized reaction rather than inflammation requiring immediate reporting.
5. An elderly client is concerned about constipation during a flight. What should the nurse recommend?
- A. Use an over-the-counter stool softener when needed
- B. Eat a high protein diet
- C. Increase the fluid intake in the diet
- D. Decrease the fat content in the diet
Correct answer: C
Rationale: The correct answer is to recommend increasing fluid intake in the diet. Adequate hydration is essential for preventing constipation, especially during travel when mobility may be reduced. Stool softeners are not the first-line recommendation and should only be used when necessary. Eating a high protein diet or decreasing fat content in the diet may not directly address the issue of constipation related to dehydration during a flight.
