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.

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.
Which intervention is appropriate to assist the patient to co pe with admission to the critical care unit?
- A. Allowing unrestricted visiting by several family members at one time
- B. Explaining all procedures in easy-to-understand terms
- C. Providing back massage and mouth care
- D. Turning down the alarm volume on the cardiac monito r
Correct Answer: B
Rationale: The correct answer is B: Explaining all procedures in easy-to-understand terms. This intervention is appropriate as it helps reduce the patient's anxiety by providing clear information about what to expect during their stay in the critical care unit. This promotes a sense of control and understanding, which can positively impact the patient's coping mechanisms.
A: Allowing unrestricted visiting by several family members at one time may overwhelm the patient and interfere with their rest and recovery.
C: Providing back massage and mouth care may be beneficial but may not directly address the patient's need for information and understanding.
D: Turning down the alarm volume on the cardiac monitor may provide a more comfortable environment but does not address the patient's emotional and psychological needs related to coping with admission to the critical care unit.
Positive end-expiratory pressure (PEEP) is a mode of ventaiblairbto.croym /atessst istance that produces which of the following conditions
- A. Each time the patient initiates a breath, the ventilator d elivers a full preset tidal volume.
- B. For each spontaneous breath taken by the patient, the tidal volume is determined by the patient’s ability to generate negative pressure.
- C. The patient must have a respiratory drive, or no breaths will be delivered.
- D. There is pressure remaining in the lungs at the end of eaxbiprbi.rcaotmio/tens tt hat is measured in cm H O.
Correct Answer: D
Rationale: The correct answer is D because positive end-expiratory pressure (PEEP) is a mode of ventilation where pressure is maintained in the lungs at the end of expiration. This helps prevent alveolar collapse and improves oxygenation. Option A is incorrect because PEEP does not deliver a full preset tidal volume with each breath initiation. Option B is incorrect because tidal volume in PEEP is not solely determined by the patient's ability to generate negative pressure. Option C is incorrect because in PEEP, breaths are delivered irrespective of the patient's respiratory drive.
A Muslim patient has been admitted to the critical care unit with complications after childbirth. Based on the Synergy Model, which nurse would be the most inappropriate to assign to care for this patient?
- A. New graduate female nurse
- B. Most experienced female nurse
- C. New graduate male nurse
- D. Female nurse with postpartum experience
Correct Answer: C
Rationale: Step-by-step rationale:
1. The Synergy Model emphasizes matching nurse competencies with patient needs.
2. A male nurse may not be culturally appropriate for a Muslim female patient due to religious beliefs.
3. Gender segregation is important in Islamic culture, especially concerning intimate care.
4. Therefore, assigning a new graduate male nurse to care for a Muslim female patient in critical condition is the most inappropriate choice.
Summary:
- Choice A is incorrect because being a new graduate does not impact cultural competence.
- Choice B is incorrect as experience does not necessarily make a nurse the best fit for a specific patient.
- Choice D is incorrect as postpartum experience is relevant, but cultural considerations are more critical in this scenario.
The nurse assesses a patient who is admitted for an overdo se of sedatives. The nurse expects to find which acid-base alteration?
- A. Hyperventilation and respiratory acidosis
- B. Hypoventilation and respiratory acidosis
- C. Hypoventilation and respiratory alkalosis
- D. Respiratory acidosis and normal oxygen levels
Correct Answer: B
Rationale: The correct answer is B: Hypoventilation and respiratory acidosis. When a patient overdoses on sedatives, it can lead to respiratory depression causing hypoventilation. Hypoventilation results in retention of CO2, leading to respiratory acidosis. This is because the body is not effectively exhaling CO2, causing an increase in carbonic acid levels and a decrease in blood pH. The other choices are incorrect because hyperventilation would lead to respiratory alkalosis (Choice A), hypoventilation does not cause respiratory alkalosis (Choice C), and normal oxygen levels do not indicate the acid-base imbalance caused by sedative overdose (Choice D).
