1. 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.

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. Which of the following descriptions best describes the function of the thyroid gland?

A. The thyroid gland converts glucose into glycogen
B. The thyroid gland secretes cortisol during times of stress
C. The thyroid gland regulates body metabolism
D. The thyroid gland affects skin pigmentation

Correct answer: C

Rationale: The thyroid gland is responsible for secreting thyroxine (T4) and triiodothyronine (T3), which work to regulate the metabolism of the body's cells. The primary function of the thyroid gland is to control the body's metabolic rate, affecting processes such as heart rate, temperature regulation, and energy levels. Choices A, B, and D are incorrect because the thyroid gland is not involved in converting glucose into glycogen, secreting cortisol, or affecting skin pigmentation. Instead, the primary role of the thyroid gland is to regulate the metabolism and energy balance in the body.

4. Which statement best describes evidence-based practice?

A. Reading and analyzing research reports to determine their implementation in nursing practice
B. Collecting data to evaluate the efficiency of nursing practice in delivering quality care
C. Monitoring unit practices to ensure adherence to Joint Commission standards
D. Using the most effective, current, and applicable information to guide nursing care for the best outcomes

Correct answer: D

Rationale: Evidence-based practice involves utilizing the most effective, current, and relevant information to inform nursing care decisions for optimal client outcomes. While research reports and data collection are important components of evidence-based practice, the essence lies in integrating all available information to determine the best course of action. Monitoring compliance with standards, as described in choices A and C, is essential for quality assurance but does not capture the comprehensive nature of evidence-based practice.

5. After change-of-shift report, which patient should the nurse assess first?

A. 72-year-old with cor pulmonale who has 4+ bilateral edema in his legs and feet
B. 28-year-old with a history of a lung transplant and a temperature of 101 F (38.3 C)
C. 40-year-old with a pleural effusion who is complaining of severe stabbing chest pain
D. 64-year-old with lung cancer and tracheal deviation after subclavian catheter insertion

Correct answer: D

Rationale: The patient with lung cancer and tracheal deviation after a subclavian catheter insertion should be assessed first. Tracheal deviation can indicate tension pneumothorax, a life-threatening condition that requires immediate intervention to prevent inadequate cardiac output or hypoxemia. While the other patients also need assessment, the potential for tension pneumothorax in the patient with tracheal deviation necessitates urgent attention to prevent complications.
