Nursing Elites

1. Which of the following clients should refrain from therapy with the thiazide diuretic hydrochlorothiazide?

• A. a client with renal impairment
• B. a client with hypertension
• C. a client with diabetes mellitus, type II
• D. a client with renal calculi (kidney stones)

Correct answer: C

Rationale: The correct answer is a client with diabetes mellitus, type II. Thiazide diuretics like hydrochlorothiazide can cause metabolic abnormalities, including elevated blood glucose levels. This increase is linked to diuretic-induced potassium deficiency, which reduces insulin secretion, leading to higher plasma glucose levels. Thiazides are commonly used in clients with renal impairment and hypertension. Moreover, thiazides decrease calcium excretion, reducing the risk of renal calculi, so it is not contraindicated for clients with kidney stones. Therefore, clients with diabetes mellitus, type II should avoid therapy with hydrochlorothiazide due to the potential adverse effects on blood glucose levels.

2. Fat emulsions are frequently administered as a part of total parenteral nutrition. Which statement is true regarding fat emulsions?

• A. They have a high energy-to-fluid-volume ratio.
• B. Even though hypertonic, they are well tolerated.
• C. They are a basic solution due to the addition of sodium hydroxide (NaOH).
• D. The pH is alkaline, making them compatible with most medications.

Correct answer: A

Rationale: The correct statement is that fat emulsions have a high energy-to-fluid-volume ratio. Fat emulsions are formulated in 10%, 20%, and 30% solutions and supply 1.1, 2, and 3 kilocalories, respectively, for each milliliter. In comparison, a milliliter of 5% dextrose only supplies 0.17 kilocalories. Choices B, C, and D are incorrect. Choice B is false because fat emulsions are essentially pH neutral and isotonic, not hypertonic. Choice C is incorrect because fat emulsions are not basic solutions; they are essentially pH neutral. Choice D is incorrect as fat emulsions are not alkaline; they are pH neutral, making them compatible with most medications.

3. Who may legally give informed consent?

• A. an 86-year-old male with advanced Alzheimer's disease
• B. a 14-year-old girl needing an appendectomy who is not an emancipated minor
• C. a 14-year-old girl needing an appendectomy who is not an emancipated minor
• D. a 6-month-old baby needing bowel surgery

Correct answer: C

Rationale: The correct answer is a 14-year-old girl needing an appendectomy who is not an emancipated minor. Informed consent can be given by individuals who are competent and not minors. Minors are generally unable to provide informed consent unless they are emancipated. Choice A is incorrect because an 86-year-old male with advanced Alzheimer's disease is considered incompetent to make decisions. Choice D is incorrect because a 6-month-old baby is unable to provide consent. Emancipated minors are an exception to the minor rule, as they can provide consent for their own treatment.

4. The nurse is preparing a client for surgery. Which item is most important to remove before sending the client to surgery?

• A. Hearing aid
• B. Contact lenses
• C. Wedding ring
• D. Artificial eye

Correct answer: B

Rationale: The correct answer is B: Contact lenses. It is crucial to remove contact lenses before surgery to prevent corneal drying, especially with non-extended wear lenses. Leaving the hearing aid or artificial eye in place does not pose harm to the client during surgery. While wedding rings are typically covered with tape, leaving them on is acceptable. Therefore, choices A, C, and D are incorrect in this scenario.

5. Why might the physician order antibiotics to be given through the central venous access device (CVAD) rather than through a peripheral IV line if the CVAD becomes infected?

• A. To prevent infiltration of the peripheral line
• B. To reduce the pain and discomfort associated with antibiotic administration in a small vein
• C. To lessen the chance of an allergic reaction to the antibiotic
• D. To attempt to eliminate microorganisms in the catheter and prevent having to remove it

Correct answer: D

Rationale: When a patient's central venous access device (CVAD) becomes infected, administering antibiotics through the line is essential to attempt to eliminate microorganisms within the catheter. The goal is to prevent the necessity of removing the catheter, which might be required if the infection persists. Choice A, 'To prevent infiltration of the peripheral line,' is incorrect as the priority is addressing the catheter infection, not preventing issues with a peripheral line. Choice B, 'To reduce the pain and discomfort associated with antibiotic administration in a small vein,' is not relevant to the rationale for choosing the CVAD for antibiotic administration. Choice C, 'To lessen the chance of an allergic reaction to the antibiotic,' is also incorrect as the main focus is managing the catheter-associated infection rather than allergy prevention.
