Nursing Elites

1. A child is seen in the emergency department for scarlet fever. Which of the following descriptions of scarlet fever is not correct?

• A. Scarlet fever is caused by infection with group A Streptococcus bacteria.
• B. "Strawberry tongue"? is a characteristic sign.
• C. Petechiae occur on the soft palate.
• D. The pharynx is red and swollen.

Correct answer: C

Rationale: Petechiae on the soft palate are not a typical finding in scarlet fever. Scarlet fever is caused by group A Streptococcus bacteria, often presenting with a strawberry tongue, red and swollen pharynx, and a sandpaper-like rash. The presence of petechiae on the soft palate is more commonly associated with conditions like rubella rather than scarlet fever. Therefore, this description is not correct in the context of scarlet fever.

2. A patient asks the nurse whether he is a good candidate to use a CPAP machine. The nurse reviews the client's history. Which condition would contraindicate the use of a CPAP machine?

• A. The patient is in the late stage of dementia.
• B. The patient has a history of bronchitis.
• C. The patient has had suicidal gestures/attempts in the past.
• D. The patient is on beta-blockers.

Correct answer: A

Rationale: The correct answer is that the patient is in the late stage of dementia. In late-stage dementia, individuals may have an inability to follow commands and understand instructions independently, which are essential for proper installation and use of a CPAP machine. This makes using a CPAP machine challenging and potentially ineffective for patients in this condition. Choice B, having a history of bronchitis, does not contraindicate the use of a CPAP machine. In fact, CPAP therapy can be beneficial for patients with respiratory conditions like bronchitis. Choice C, a history of suicidal gestures/attempts, while concerning for the patient's mental health, does not directly contraindicate the use of a CPAP machine. Choice D, being on beta-blockers, is not a contraindication for CPAP machine use. Beta-blockers are commonly used medications for various conditions and do not interfere with the use of a CPAP machine.

3. A client complained of nausea, a metallic taste in her mouth, and fine hand tremors 2 hours after her first dose of lithium carbonate (Lithane). What is the nurse's best explanation of these findings?

• A. These side effects are common and should subside in a few days.
• B. The client is probably having an allergic reaction and should discontinue the drug.
• C. Taking the lithium on an empty stomach should decrease these symptoms.
• D. Decreasing dietary intake of sodium and fluids should minimize the side effects.

Correct answer: A

Rationale: The correct answer is, 'These side effects are common and should subside in a few days.' Nausea, metallic taste, and fine hand tremors are common side effects of lithium carbonate (Lithane) and typically diminish within a few days as the body adjusts to the medication. Option B is incorrect because these symptoms are not indicative of an allergic reaction. Option C is incorrect as taking lithium on an empty stomach does not directly address or decrease these specific side effects. Option D is also incorrect as reducing sodium and fluid intake is not the recommended approach to managing these particular side effects of lithium.

4. The healthcare provider is caring for a 20 lbs (9 kg) 6-month-old with a 3-day history of diarrhea, occasional vomiting, and fever. Peripheral intravenous therapy has been initiated, with 5% dextrose in 0.33% normal saline with 20 mEq of potassium per liter infusing at 35 ml/hr. Which finding should be reported to the healthcare provider immediately?

• A. 3 episodes of vomiting in 1 hour
• B. Periodic crying and irritability
• C. Vigorous sucking on a pacifier
• D. No measurable voiding in 4 hours

Correct answer: D

Rationale: The correct answer is 'No measurable voiding in 4 hours.' This finding should be reported to the healthcare provider immediately. The concern is the possibility of hyperkalemia, which could occur with continued potassium administration and a decrease in urinary output since potassium is excreted via the kidneys. It is crucial to monitor urinary output in pediatric patients receiving potassium-containing IV solutions to prevent electrolyte imbalances and potential complications. Choices A, B, and C are not the most critical findings that require immediate reporting. '3 episodes of vomiting in 1 hour' may suggest a need for antiemetic therapy or further assessment of the underlying cause but does not pose an immediate risk like the potential electrolyte imbalance from decreased urinary output. 'Periodic crying and irritability' and 'Vigorous sucking on a pacifier' are common behaviors in infants and are not indicative of a critical condition that requires urgent attention in this scenario.

5. Which response by the nurse best explains the purpose of ranitidine (Zantac) for a patient admitted with bleeding esophageal varices?

• A. The medication will reduce the risk of aspiration.
• B. The medication will inhibit the development of gastric ulcers.
• C. The medication will prevent irritation of the enlarged veins.
• D. The medication will decrease nausea and improve appetite.

Correct answer: C

Rationale: The correct answer is: 'The medication will prevent irritation of the enlarged veins.' Esophageal varices are dilated submucosal veins. The therapeutic action of H2-receptor blockers in patients with esophageal varices is to prevent irritation and bleeding from the varices caused by reflux of acidic gastric contents. While ranitidine can decrease the risk of peptic ulcers, reduce nausea, and help prevent aspiration pneumonia, the primary purpose of H2-receptor blockade in this patient is to prevent irritation and bleeding from the varices, not the other listed effects.
