Safe and Effective Care Environment NCLEX RN Questions

1. One of your patients is dependent on a mechanical ventilator for their respiratory needs. The patient cannot breathe on their own. Suddenly, the lights in the patient's room and the entire nursing unit go off. You realize that the electric power has been lost. What is the first thing that you should do for this patient?

A. Plug the ventilator into the red outlet in the room.
B. Plug the ventilator into the blue outlet in the room.
C. Use an Ambu bag to ventilate the patient.
D. Call the doctor about this emergency.

Correct answer: B

Rationale: In healthcare facilities, emergency generators are in place in case of power outages. The red outlets in patient rooms are connected to the emergency generator and provide power during such situations. By plugging the ventilator into the red outlet, you ensure that the patient's mechanical ventilation needs are met despite the power loss. Using an Ambu bag or calling the doctor should be secondary actions after ensuring the ventilator is powered correctly. Plugging the ventilator into the blue outlet is incorrect and can result in the ventilator not functioning during a power outage.

2. The student observes a patient with no breathing problems. Which action by the student indicates a need to review respiratory assessment skills?

A. The student starts at the apices of the lungs and moves to the bases.
B. The student compares breath sounds from side to side, avoiding bony areas.
C. The student places the stethoscope over the posterior chest and listens during expiration.
D. The student instructs the patient to breathe slowly and a little more deeply than normal through the mouth.

Correct answer: C

Rationale: The correct answer is C. Listening only during inspiration instead of both inspiration and expiration indicates a need for a review of respiratory assessment skills. During chest auscultation, it is essential to listen to at least one cycle of inspiration and expiration at each placement of the stethoscope. Instructing the patient to breathe slowly and a little deeper than normal through the mouth is a correct practice during auscultation. The correct sequence for lung auscultation is from the apices to the bases, comparing breath sounds bilaterally, avoiding bony areas. It is crucial to place the stethoscope over lung tissue rather than bony prominences to accurately assess lung sounds.

3. The nurse is conducting a health fair for older adults. Which statement is true regarding vital sign measurements in aging adults?

A. The pulse is easier to palpate due to the rigidity of the blood vessels.
B. An increased respiratory rate and a shallower inspiratory phase are expected findings.
C. A widened pulse pressure occurs from changes in the systolic and diastolic blood pressures.
D. Changes in the body's temperature regulatory mechanism decrease the older adult's likelihood of developing a fever.

Correct answer: B

Rationale: Aging causes a decrease in vital capacity and decreased inspiratory reserve volume. As a result, the examiner may observe a shallower inspiratory phase and an increased respiratory rate in older adults. Contrary to common belief, the increased rigidity of arterial walls actually makes the pulse easier to palpate in aging adults. Pulse pressure is widened, not decreased, due to changes in systolic and diastolic blood pressures. Furthermore, changes in the body's temperature regulatory mechanism make older individuals less likely to develop a fever but more susceptible to hypothermia.

4. You are taking care of 7 patients today. One of your residents wants water; another needs help walking to the bathroom; another just stated that they have chest pain; and another is crying because his daughter did not visit him today. Which patient care task is the lowest in terms of priority?

A. The water
B. Help to the bathroom
C. The chest pain
D. The crying person

Correct answer: D

Rationale: The lowest priority patient care task in this scenario is addressing the emotional need of the patient who is crying because his daughter did not visit him today. While emotional support is important, the other needs - providing water, assisting to the bathroom, and addressing chest pain - are physical needs that must take priority as they directly impact the patient's well-being and health. It is crucial to acknowledge and address emotional needs but in this situation, the physical needs of the patients should be addressed first.

5. When are manual hematocrits done?

A. to monitor anemia
B. by using a microhematocrit tube.
C. to measure the percentage of plasma to cells.
D. All of the above.

Correct answer: D

Rationale: Manual hematocrits are performed to monitor anemia, which involves measuring the percentage of red blood cells in the blood. The process involves collecting blood in a microhematocrit tube, then centrifuging it to separate the plasma from the cells. By measuring the ratio of plasma to cells, healthcare providers can assess the patient's hematocrit level. Therefore, all the provided options are correct as they collectively describe the purpose and procedure of manual hematocrits.
