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. A two-year-old has been in the hospital for 3 weeks and has seldom seen family members due to isolation precautions. Which of the following hospitalization changes is most likely to be occurring?

• A. Guilt
• B. Trust
• C. Separation anxiety
• D. Shame

Correct answer: C

Rationale: The correct answer is 'Separation anxiety.' Separation anxiety is a common response in young children when they are separated from their primary caregivers for extended periods. In this case, the two-year-old being in the hospital for three weeks and not being able to see family members due to isolation precautions can trigger separation anxiety. 'Guilt' is a feeling of responsibility for wrongdoing, which is not the most likely change occurring in this scenario. 'Trust' involves reliance and confidence in others, not typically associated with prolonged separation from family. 'Shame' is a negative emotion related to feeling disgrace, which is not the most appropriate response in this hospitalization situation.

3. The client is diagnosed with multiple myeloma. The doctor has ordered cyclophosphamide (Cytoxan). Which instruction should be given to the client?

• A. "Walk about a mile a day to prevent calcium loss."?
• B. "Increase the fiber in your diet."?
• C. "Report nausea to the doctor immediately."?
• D. "Drink at least eight large glasses of water a day."?

Correct answer: D

Rationale: Cyclophosphamide (Cytoxan) can cause hemorrhagic cystitis, a condition characterized by inflammation of the bladder wall leading to bleeding. To prevent this complication, the client should drink at least eight glasses of water a day. Walking to prevent calcium loss (choice A) and increasing fiber intake (choice B) are not directly related to the side effects of Cytoxan, making them unnecessary instructions in this case. While nausea is a common side effect of chemotherapy, the immediate reporting of nausea to the doctor (choice C) is important but not specifically related to the use of Cytoxan in this scenario.

4. A home health nurse is making preparations for morning visits. Which one of the following clients should the nurse visit first?

• A. A client with brain attack (stroke) receiving tube feedings
• B. A client with congestive heart failure complaining of nighttime dyspnea
• C. A client who had a thoracotomy 6 months ago
• D. A client with Parkinson’s disease

Correct answer: B

Rationale: The correct answer is B. The client with congestive heart failure complaining of nighttime dyspnea should be seen first as airway management is a priority in nursing care. This client's symptoms indicate potential respiratory distress, requiring immediate attention. Choices A, C, and D involve clients who are more stable and do not present with urgent or acute conditions that require immediate intervention. Choice A with a client receiving tube feedings for a stroke may require attention, but the urgency of addressing potential respiratory distress in choice B takes precedence. Choice C, a client who had a thoracotomy 6 months ago, unless presenting with acute distress, does not necessitate immediate attention. Choice D, a client with Parkinson's disease, is usually a chronic condition that does not typically require immediate intervention for the described scenario.

5. 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.
