Safe and Effective Care Environment NCLEX RN Questions

1. What is the first aid for frostbite?

A. Running cold water over the affected area. Warm or hot water will shock the area and cause more tissue damage.
B. Run warm water over the area to rapidly rewarm the affected area.
C. Run hot water over the area to warm the area as quickly as possible.
D. Cover the area with a blanket, using a heating pad if the blanket isn't warm enough.

Correct answer: A

Rationale: First aid for frostbite involves running cold water over the affected area. It is important to avoid warm or hot water as it can shock the area and cause further tissue damage. Warm water should not be used to rapidly rewarm the affected area. Similarly, hot water should also be avoided as it can warm the area too quickly and potentially cause harm. Covering the area with a blanket and using a heating pad may not be effective and can even lead to more damage. Seeking medical assistance is crucial if the tissue appears necrotic to prevent further complications.

2. Which brain structure serves as the heat-regulating center?

A. Hypothalamus
B. Pituitary Gland
C. Pons
D. Medulla Oblongata

Correct answer: A

Rationale: The correct answer is the Hypothalamus. The hypothalamus is responsible for regulating body temperature, ensuring it stays within a narrow range. Moreover, the hypothalamus controls various essential bodily functions, such as hunger, thirst, and circadian rhythms. Choices B, C, and D are incorrect because the Pituitary Gland primarily produces and releases hormones, the Pons is involved in functions like sleep, respiration, and bladder control, and the Medulla Oblongata controls vital functions like breathing and heart rate, but not body temperature regulation.

3. What is the most effective step in hand washing?

A. Using friction to remove potential pathogens.
B. Using hospital-grade soap.
C. Moisturizing the hands after washing to prevent cracking.
D. Washing hands with soap for at least 15 seconds.

Correct answer: A

Rationale: The most effective step in hand washing is using friction to remove potential pathogens. While using soap, moisturizing hands, and washing for a sufficient duration are important aspects of hand hygiene, the mechanical action of rubbing hands together with friction is crucial in dislodging and removing dirt, debris, and potential pathogens. Hospital-grade soap may be beneficial, but the physical act of friction is key to effective hand washing. Moisturizing after washing is important for skin health but not the most effective step in the hand washing process. Simply washing hands for a specific duration, such as 15 seconds, without proper friction may not effectively remove contaminants. Therefore, using friction for thorough cleaning is the most crucial step in hand washing.

4. An adult patient is at the clinic for a physical examination. The patient states that they are feeling 'very anxious' about the physical examination. What steps can the nurse take to make the patient more comfortable?

A. Appear unhurried and confident when examining the patient.
B. Leave the room when the patient undresses unless they need assistance.
C. Ask the patient to change into an examining gown and to leave their undergarments on.
D. Measure vital signs at the beginning of the examination to gradually accustom the patient.

Correct answer: A

Rationale: To help alleviate the patient's anxiety, the nurse should appear unhurried and confident during the examination. This can make the patient feel more at ease and reassured. It is important for the nurse to respect the patient's privacy by leaving the room while the patient changes unless assistance is needed. The patient should be instructed to change into an examining gown while leaving their undergarments on, providing a sense of comfort and familiarity. Additionally, measuring vital signs at the beginning of the examination can help gradually acclimate the patient to the process, making it less overwhelming. Therefore, the correct answer is to appear unhurried and confident when examining the patient. Choices B, C, and D are incorrect because they do not directly address the patient's anxiety or provide comfort in the same way as the correct answer.

5. What term is used to describe the sexual response changes among middle-aged men?

A. Menopause
B. Climacteric
C. Generativity
D. Maturity

Correct answer: B

Rationale: The correct answer is 'Climacteric.' Climacteric specifically refers to the period in middle-aged men characterized by sexual response changes, such as delayed arousal. Menopause, choice A, is incorrect as it is specific to women and marks the cessation of menstrual periods. Generativity, choice C, is unrelated as it refers to the concern for guiding the next generation. Maturity, choice D, is too broad and generally refers to reaching the adult stage of development, not specifically addressing sexual response changes in middle-aged men.
