Safe and Effective Care Environment NCLEX RN Questions

1. What is the primary route of transmission of MRSA?

A. Shared needles
B. Hands of healthcare workers
C. Items in the healthcare environment
D. Blood transfusions

Correct answer: B

Rationale: The correct answer is 'Hands of healthcare workers.' MRSA is primarily transmitted via the unwashed hands of healthcare workers who can carry the Staphylococcus aureus bacterium from one patient to another. Shared needles, items in the healthcare environment, and blood transfusions are not the main routes of transmission for MRSA. Shared needles can transmit bloodborne pathogens, items in the healthcare environment can harbor bacteria but are not the primary mode for MRSA, and blood transfusions are not a common route for MRSA transmission.

2. You are taking care of a patient who has active TB. The patient has been put on airborne precautions and is in a special room. You must wear a HEPA mask when you enter the room. Now, the patient has to leave the room and go to the radiology department. How can you transport this patient to the radiology department without spreading TB throughout the hospital?

A. Have everyone along the route to the radiology department wear a HEPA mask.
B. Have patients along the route to the radiology department wear a HEPA mask.
C. Have staff along the route to the radiology department wear a HEPA mask.
D. Place a HEPA mask on the patient.

Correct answer: D

Rationale: To prevent the spread of TB throughout the hospital, it is essential to place a HEPA mask on the patient before transporting them to the radiology department. Expecting everyone along the route to wear a HEPA mask is not practical due to the high cost and the need for special fittings. Having patients or staff wear HEPA masks along the route is also not feasible and may not effectively contain the spread of TB.

3. A physician has ordered that a client must be placed in a high Fowler's position. How does the nurse position this client?

A. The client is placed face-down
B. The client lies on his back with his head lower than his feet
C. The client lies on his back with the knees drawn up toward the chest
D. The client is sitting with the backrest at a 90-degree angle

Correct answer: D

Rationale: A high Fowler's position is a modification of the semi-Fowler's position, in which the client is seated with arms resting at the sides or in the lap. The high Fowler's position requires that the client's head and upper chest are elevated, and the backrest is at a 90-degree angle. This position supports breathing and appropriate chest wall movement, making it easier for the client to breathe. Choices A, B, and C are incorrect because a high Fowler's position involves the client being in a sitting position with the backrest at a 90-degree angle, not being face-down, lying with the head lower than the feet, or lying on the back with knees drawn up towards the chest.

4. The nurse is preparing to assess a hospitalized patient who is experiencing significant shortness of breath. How should the nurse proceed with the assessment?

A. Have the patient lie down to obtain an accurate cardiac, respiratory, and abdominal assessment.
B. Obtain a thorough history and physical assessment from the patient's family member.
C. Immediately perform a complete history and physical assessment to obtain baseline information.
D. Examine the body areas relevant to the problem and complete the rest of the assessment after the problem has resolved.

Correct answer: D

Rationale: When assessing a patient experiencing significant shortness of breath, it is crucial to prioritize the evaluation of areas directly related to the problem. Having the patient lie down may exacerbate the breathing difficulty. Therefore, the nurse should focus on examining the body areas pertinent to the issue, such as the respiratory and cardiac systems. Completing the rest of the assessment can be deferred until after addressing the immediate problem. Obtaining a complete history or involving family members should come after addressing the acute issue to ensure the patient's safety and comfort.

5. A client is diagnosed with ariboflavinosis. Which of the following foods should the nurse serve this client?

A. Citrus fruits
B. Milk
C. Fish
D. Potatoes

Correct answer: B

Rationale: Ariboflavinosis is a vitamin B-2 deficiency. Symptoms may include cracks around the mouth, inflammation of the tongue, or light sensitivity. Foods rich in vitamin B-2, like milk, liver, green vegetables, or whole grains, are recommended. Citrus fruits (choice A) are good sources of vitamin C, not B-2. Fish (choice C) is a source of protein and omega-3 fatty acids but not a significant source of vitamin B-2. Potatoes (choice D) are a source of carbohydrates but do not provide high levels of vitamin B-2.
