Nursing Elites

1. Diabetes insipidus is the result of:

• A. A diet high in sugar and carbohydrates.
• B. A complicated pregnancy.
• C. A disorder of the pancreas.
• D. A disorder of the pituitary gland.

Correct answer: D

Rationale: Diabetes insipidus is caused by a disorder of the pituitary gland affecting ADH regulation. This disorder results in the decreased production or release of antidiuretic hormone (ADH), leading to the inability of the kidneys to concentrate urine properly. Choices A, B, and C are incorrect as they do not relate to the underlying cause of diabetes insipidus.

2. Which skin disorder most closely resembles and mimics dandruff?

• A. Lice infestation
• B. Scabies
• C. Dermatitis
• D. Acne vulgaris

Correct answer: C

Rationale: Dermatitis can closely resemble and mimic dandruff due to similar symptoms like flaking and itching. Lice infestation (choice A) is characterized by the presence of lice and their eggs attached to the hair shaft, different from dandruff. Scabies (choice B) is a contagious skin condition caused by mites, presenting as burrows, rashes, and intense itching, not typically resembling dandruff. Acne vulgaris (choice D) is a skin condition involving hair follicles and sebaceous glands, manifesting as pimples and inflammation, which is distinct from dandruff.

3. What is the most common cause of HHNS?

• A. Insulin overdose
• B. Removal of the adrenal gland
• C. Undiagnosed, untreated hyperpituitarism
• D. Undiagnosed, untreated diabetes mellitus

Correct answer: D

Rationale: The correct answer is D: Undiagnosed, untreated diabetes mellitus. Hyperosmolar hyperglycemic nonketotic syndrome (HHNS) is most commonly caused by undiagnosed and untreated diabetes mellitus. Insulin overdose (Choice A) is not a typical cause of HHNS; it is more related to hypoglycemia. Removal of the adrenal gland (Choice B) can lead to adrenal insufficiency but is not a common cause of HHNS. Undiagnosed, untreated hyperpituitarism (Choice C) is not a usual cause of HHNS; it is more related to pituitary hormone imbalances rather than hyperglycemia.

4. The doctor has ordered 20 cc per hour of normal saline intravenously for your pediatric patient. You will be using pediatric intravenous tubing that delivers 60 cc per drop. How many drops per minute will you administer using this pediatric intravenous set?

• A. 30 drops per minute
• B. 25 drops per minute
• C. 20 drops per minute
• D. 22 drops per minute

Correct answer: C

Rationale: To calculate the drops per minute, first convert the ordered amount to drops per minute. 20 cc per hour equals 20 drops per hour with 60 cc per drop tubing, which is equivalent to 20 drops per hour * 60 cc per drop = 1200 drops per hour. To find drops per minute, divide 1200 by 60 (minutes in an hour), which equals 20 drops per minute. Therefore, the correct answer is 20 drops per minute. Choices A, B, and D are incorrect as they do not reflect the correct calculation based on the provided information.

5. A nurse is caring for a client who is unconscious and whose partner is their health care surrogate. The partner wishes to discontinue the client's feeding tube, but another family member tells the nurse that they want the client to continue receiving treatment. Which of the following responses should the nurse make?

• A. You should contact the provider about your wishes for your family member.
• B. We'll need to have the nursing supervisor review the client's advance directives.
• C. You should speak with the facility's ethics committee about your concerns.
• D. As the health care surrogate, the client's partner can make this decision.

Correct answer: D

Rationale: The correct response is D because the health care surrogate, as designated by the client, has the legal authority to make healthcare decisions on behalf of the client when they are unable to do so. This authority includes decisions about treatment continuation or withdrawal. Option A is incorrect as the family member's wishes do not override the legal authority of the health care surrogate. Option B is not the most appropriate action in this situation as the advance directives are already clear by the designation of a health care surrogate. Option C is not necessary at this stage since the health care surrogate can make the decision without involving the ethics committee.
