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. A client is about to have a TENS unit attached for pain relief. Which of the following actions is most appropriate in this situation?

A. Inform the client that he may experience tingling sensations.
B. Connect the TENS unit before the client goes to bed for the night.
C. Inform the client that the TENS unit may have pain-reducing effects for 10 to 15 days.
D. After treatment, inform the client that he may not use a TENS unit again for at least 2 weeks.

Correct answer: A

Rationale: When attaching a TENS unit for pain relief, it is essential to inform the client that he may experience tingling sensations. This is a common sensation experienced when using a TENS unit, but it should not cause muscle twitching. The therapeutic effects of a TENS unit usually last between 3 to 5 days. Choice B is incorrect because there is no specific recommendation to connect the TENS unit before bedtime. Choice C is incorrect as stating that the TENS unit may have pain-reducing effects for 10 to 15 days is inaccurate, as the effects typically last 3 to 5 days. Choice D is incorrect because there is no guideline suggesting that the client cannot use a TENS unit again for at least 2 weeks after treatment.

3. When a sequence of repeated weights is necessary, the healthcare provider should aim to weigh the patient at the same time of day and with consistent clothing. Using a standardized balance or electronic standing scale is recommended for accurate measurements. The patient should remove shoes and heavy outer clothing. It is not required for the patient to always be weighed in undergarments. What is the most appropriate indicator of the patient's overall well-being?

A. General health
B. Genetic makeup
C. Nutritional status
D. Activity and exercise patterns

Correct answer: A

Rationale: Weight measurements are essential to assess general health, particularly in monitoring growth patterns. Height and weight recordings are crucial indicators of overall well-being, reflecting the individual's health status. Genetic makeup does not change with weight fluctuations, making it an inappropriate indicator. Nutritional status and activity levels can influence weight but are not as comprehensive as general health in reflecting overall well-being.

4. While auscultating heart sounds, the nurse hears a murmur. Which of these instruments would be used to assess this murmur?

A. Electrocardiogram
B. Bell of the stethoscope
C. Diaphragm of the stethoscope
D. Palpation with the nurse's palm of the hand

Correct answer: B

Rationale: The correct instrument to assess a murmur while auscultating heart sounds is the bell of the stethoscope. An electrocardiogram is used to measure the heart's electrical activity, not to assess murmurs. Palpation with the nurse's palm of the hand is a method to assess pulses or textures, not heart murmurs. The diaphragm of the stethoscope is typically used for high-pitched sounds like breath, bowel, and normal heart sounds, whereas the bell is more suitable for soft, low-pitched sounds such as murmurs or extra heart sounds.

5. A 51-year-old woman had an incisional cholecystectomy 6 hours ago. The nurse will place the highest priority on assisting the patient to

A. choose low-fat foods from the menu
B. perform leg exercises hourly while awake
C. ambulate the evening of the operative day
D. turn, cough, and deep breathe every 2 hours

Correct answer: D

Rationale: Postoperative nursing care after a cholecystectomy focuses on preventing respiratory complications due to the surgical incision being high in the abdomen, which impairs coughing and deep breathing. Turning, coughing, and deep breathing every 2 hours help prevent respiratory complications, such as pneumonia. While choices A, B, and C are also important aspects of postoperative care, they are not as high a priority as ensuring proper ventilation and respiratory function in the immediate postoperative period.
