1. Which of the following is not a function of parathyroid hormone?

• A. moving calcium from bones to the bloodstream
• B. inhibiting renal tubular reabsorption of phosphorus
• C. promoting renal tubular reabsorption of calcium
• D. enhancing renal production of vitamin D metabolites

Correct answer: B

Rationale: The correct answer is 'inhibiting renal tubular reabsorption of phosphorus.' Parathyroid hormone actually inhibits renal tubular reabsorption of phosphorus, making this choice the opposite of its function. Parathyroid hormone functions to move calcium from bones to the bloodstream (Choice A), promote renal tubular reabsorption of calcium (Choice C), and enhance renal production of vitamin D metabolites (Choice D). Therefore, all other choices are functions of parathyroid hormone except for the inhibition of phosphorus reabsorption.

2. What is a predisposing factor for cancer of the tongue?

• A. tobacco use
• B. obesity
• C. sun exposure
• D. eating sweets

Correct answer: A

Rationale: Tobacco use is a well-established predisposing factor for cancer of the tongue. Smoking or chewing tobacco can lead to the development of oral cancers, including those affecting the tongue. Obesity, sun exposure, and eating sweets are not directly linked to an increased risk of tongue cancer. Obesity may be associated with other types of cancer, sun exposure can lead to skin cancer, and eating sweets is not a known risk factor for tongue cancer. Therefore, the correct answer is tobacco use, as it has a strong association with the development of tongue cancer, making it a significant predisposing factor.

3. When a client has a chest drainage system in place, where should the system be placed?

• A. above the level of the client's chest
• B. at the level of the client's shoulders
• C. at the level of the chest
• D. below the level of the chest

Correct answer: D

Rationale: A chest drainage system should be placed below the level of the client's chest to ensure proper drainage of fluid from the chest. Placing the system above the level of the chest or at the shoulders would not allow gravity to assist in the drainage process, potentially leading to complications such as fluid accumulation. Similarly, placing it at the level of the chest would not create the necessary gravity-dependent flow for effective drainage, which is crucial for the proper functioning of the chest drainage system.

4. During an annual physical exam, a client is diagnosed with Benign Prostatic Hyperplasia (BPH). This client is likely to have a consult with which type of physician?

• A. gynecologist
• B. physiatrist
• C. urologist
• D. proctologist

Correct answer: C

Rationale: A client diagnosed with Benign Prostatic Hyperplasia (BPH) would typically have a consult with a urologist. Urologists specialize in urinary tract and prostatic diseases, making them the appropriate choice for managing BPH. A gynecologist focuses on diseases of the female reproductive tract, so they are not relevant in this case. A physiatrist specializes in rehabilitation care, which is not directly related to the treatment of BPH. A proctologist specializes in lower colonic digestive diseases, which are unrelated to BPH.

5. A nurse on the night shift is making client rounds. When the nurse checks a client who is 97 years old and has successfully been treated for heart failure, he notes that the client is not breathing. If the client does not have a do-not-resuscitate (DNR) order, the nurse should take which action?

• A. Administer cardiopulmonary resuscitation (CPR)
• B. Call the client's health care provider
• C. Administer oxygen to the client and call the health care provider
• D. Contact the nursing supervisor for directions

Correct answer: A

Rationale: Administering cardiopulmonary resuscitation (CPR) is the appropriate action when a client is not breathing and does not have a do-not-resuscitate (DNR) order. CPR is considered an emergency treatment that can be provided without client consent in life-threatening situations. Calling the health care provider or nursing supervisor for directions, as well as administering oxygen without addressing the lack of breathing, would delay critical life-saving interventions. Therefore, administering CPR is the most urgent and necessary action to perform in this scenario.
