A nurse is directed to administer a hypotonic intravenous solution. The nurse expects that compensatory mechanisms associated with hypovolemia would cause all of the following symptoms except:

Correct Answer: C

Rationale: The correct answer is C: 0.90% sodium chloride. When administering a hypotonic solution like 0.45% sodium chloride or 5% dextrose in water, water moves into the cells causing them to swell. This can exacerbate symptoms of hypovolemia such as low blood pressure and decreased perfusion. However, 0.90% sodium chloride is an isotonic solution and will not further exacerbate hypovolemic symptoms. Choices A, B, and D are hypotonic solutions that can worsen hypovolemic symptoms by causing cellular swelling.

Correct Answer: B

Rationale: The correct answer is B (10-15 mmHg) because this range is considered safe and effective for suctioning in most cases. Lower suction pressures (such as 2-5 mmHg) may not effectively clear secretions, while higher pressures (20-25 mmHg) can cause tissue damage. Choice C (5-10 mmHg) falls within the safe range but may not provide enough suction for effective clearance. Therefore, the optimal suction pressure for James using the portable suction unit at home is 10-15 mmHg.

Correct Answer: C

Rationale: The correct answer is C: Cheese. Cheese is high in sodium and should be avoided on a low-sodium diet. Sodium can contribute to high blood pressure and other health issues. Apples, chicken, and broccoli are all low in sodium and can be included in a low-sodium diet. Cheese is the only option that is high in sodium, making it the correct choice to avoid.

Correct Answer: B

Rationale: The correct answer is B: 17 drops per minute. To calculate the correct drip rate, you need to use the formula: (Volume to be infused in mL / Time in minutes) x Drop factor. In this case, if the volume to be infused is 100 mL and the time is 60 minutes with a drop factor of 20, the calculation would be: (100 / 60) x 20 = 33.33 drops per minute. Since we cannot deliver fractional drops, the closest whole number is 17 drops per minute. This ensures the correct delivery rate for the medication. Choice A (6 drops per minute) is incorrect as it would be too slow and may not deliver the medication effectively. Choice C (50 drops per minute) and Choice D (100 drops per minute) are incorrect as they would both deliver the medication too quickly, potentially causing harm to the patient. The correct answer, 17 drops per minute, ensures a safe and accurate delivery rate

Correct Answer: D

Rationale: The correct answer is D - Check for a gag reflex before allowing the patient to drink. This is important after a bronchoscopy to prevent aspiration. Step 1: Assessing gag reflex ensures the patient can protect their airway. Step 2: Aspiration risk is high post-bronchoscopy due to sedation and possible throat numbness. Step 3: Allowing fluids without confirming gag reflex can lead to aspiration pneumonia. Other choices are incorrect. A: Ordering a meal immediately is inappropriate after NPO period. B: Encouraging fluids without assessing gag reflex may lead to aspiration. C: Monitoring consciousness is important but not directly related to post-bronchoscopy care.
