A nurse is weaning a 68-kg male patient who has chronic obstructive pulmonary disease (COPD) from mechanical ventilation. Which patient assessment finding indicates that the weaning protocol should be stopped?
- A. The patient’s heart rate is 97 beats/min.
- B. The patient’s oxygen saturation is 93%.
- C. The patient’s respiratory rate is 32 breaths/min.
- D. The patient’s spontaneous tidal volume is 450 mL.
Correct Answer: C
Rationale: The correct answer is C because a respiratory rate of 32 breaths/min indicates increased work of breathing, which could be a sign of respiratory distress. In a patient being weaned from mechanical ventilation, an elevated respiratory rate suggests that the patient may not be able to sustain adequate ventilation on their own. This warrants stopping the weaning protocol to prevent respiratory failure.
Choice A is incorrect because a heart rate of 97 beats/min is within normal range for an adult. Choice B is incorrect because an oxygen saturation of 93% is acceptable for a patient with COPD. Choice D is incorrect because a tidal volume of 450 mL is adequate for a patient weaning from mechanical ventilation.

The nurse is caring for a critically ill patient with a very concerned family. Given that the family is under high stress, what nursing intervention will best ameliorate their stress while preserving independence?
- A. Encourage the family to participate in patient care tasks.
- B. Teach the family to ask questions of the health care team.
- C. Ask the family to select a family representative for communication.
- D. Limit visits to immediate family members for limited times.
Correct Answer: A
Rationale: The correct answer is A: Encourage the family to participate in patient care tasks. This intervention helps to alleviate stress by involving the family in care, promoting a sense of control and empowerment. It also fosters a collaborative relationship between the family and healthcare team. The other choices are incorrect because B only focuses on asking questions but doesn't actively involve the family in care. C may add pressure on the selected representative and exclude others. D limits family involvement and may increase stress by restricting visitation.
A patient with hypotension and an elevated temperature after working outside on a hot day is treated in the emergency department (ED). The nurse determines that discharge teaching has been effective when the patient makes which statement?
- A. I will take salt tablets when I work outdoors in the summer.
- B. I should take acetaminophen (Tylenol) if I start to feel too warm.
- C. I should drink sports drinks when working outside in hot weather.
- D. I will move to a cool environment if I notice that I am feeling confused.
Correct Answer: C
Rationale: The correct answer is C: "I should drink sports drinks when working outside in hot weather." This statement is correct because hypotension and elevated temperature could indicate dehydration and electrolyte imbalance due to excessive sweating in hot weather. Drinking sports drinks can help replenish electrolytes lost through sweating and prevent dehydration.
Incorrect choices:
A: Taking salt tablets can lead to an imbalance in electrolytes and worsen the condition.
B: Acetaminophen can lower fever but does not address dehydration or electrolyte imbalance.
D: Moving to a cool environment when feeling confused is important but does not address the underlying issue of dehydration and electrolyte imbalance.
Which assessment finding obtained by the nurse when caring for a patient with a right radial arterial line indicates a need for the nurse to take immediate action?
- A. The right hand is cooler than the left.
- B. The mean arterial pressure (MAP) is 77 mm Hg.
- C. The system is delivering 3 mL of flush solution per hour.
- D. The flush bag and tubing were last changed 3 days previously.
Correct Answer: A
Rationale: The correct answer is A because a cooler right hand may indicate compromised circulation, potentially due to arterial occlusion or clot formation. This could lead to inadequate perfusion and tissue damage. Immediate action is needed to assess and address the cause.
Choice B is incorrect because a MAP of 77 mm Hg is within the normal range for most patients and does not require immediate action.
Choice C is incorrect as delivering 3 mL of flush solution per hour is an appropriate rate and does not indicate a need for immediate action.
Choice D is incorrect as the flush bag and tubing being changed 3 days ago does not necessarily indicate an immediate issue with the arterial line function.
The nurse recognizes that which patient is likely to benefit most from patient-controlled analgesia?
- A. 21-year-old with a C4 fracture and quadriplegia
- B. 45-year-old with femur fracture and closed head injury
- C. 59-year-old postoperative elective bariatric surgery
- D. 70-year-old postoperative cardiac surgery; mild demen tia
Correct Answer: A
Rationale: The correct answer is A, the 21-year-old with a C4 fracture and quadriplegia. This patient is likely to benefit most from patient-controlled analgesia (PCA) due to the inability to self-administer traditional pain medications. With quadriplegia, the patient may have limited mobility and sensation, making it challenging to communicate pain levels effectively. PCA allows the patient to control their pain relief within preset limits, enhancing autonomy and optimizing pain management.
Summary:
- Choice B: The 45-year-old with femur fracture and closed head injury may benefit from PCA, but the severity of the head injury could affect their ability to use the device effectively.
- Choice C: The 59-year-old postoperative elective bariatric surgery patient can typically manage pain with traditional methods postoperatively.
- Choice D: The 70-year-old postoperative cardiac surgery patient with mild dementia may have the cognitive ability to use PCA but could potentially benefit more from other pain management strategies due
In calculating the glomerular filtration rate (GFR) results for women, the creatinine clearance is usually:
- A. the same as for men.
- B. greater than that for men.
- C. multiplied by 0.85
- D. multiplied by 1.15.
Correct Answer: C
Rationale: The correct answer is C: multiplied by 0.85. This is because women typically have lower muscle mass compared to men, resulting in lower creatinine production. Therefore, to adjust for this difference, the creatinine clearance for women is multiplied by 0.85. This correction factor helps to more accurately estimate the GFR in women.
Choices A and B are incorrect because the creatinine clearance for women is not the same as or greater than that for men due to the physiological differences in muscle mass. Choice D is also incorrect as multiplying by 1.15 would overestimate the GFR in women.
