Nursing Elites

1. A patient develops hypotension, laryngeal edema, and bronchospasm after eating peanuts. Which medication should the nurse prepare to administer?

• A. Promethazine
• B. Epinephrine
• C. Diphenhydramine
• D. Hydroxyzine

Correct answer: B

Rationale: The patient is exhibiting symptoms of anaphylaxis triggered by a peanut allergy, a severe and potentially life-threatening allergic reaction. The appropriate medication for anaphylaxis is epinephrine. Epinephrine acts quickly to reverse the symptoms by constricting blood vessels, relaxing bronchial muscles, and reducing laryngeal edema, making it the drug of choice for this situation. Promethazine, diphenhydramine, and hydroxyzine are not the first-line treatments for anaphylaxis. Promethazine is an antihistamine with sedative effects, Diphenhydramine is an antihistamine, and Hydroxyzine is also an antihistamine with sedative properties. While these medications can help with mild allergic reactions, they are not as effective or fast-acting as epinephrine in treating the severe manifestations of anaphylaxis.

2. During a well-child visit, a nurse is assessing a three-year-old toddler. Which of the following manifestations should the nurse report to the provider?

• A. Blood pressure 90/50
• B. Respiratory rate 45/min
• C. Weight 14.5 kg or 32 lb
• D. Heart rate 110/min

Correct answer: B

Rationale: A respiratory rate of 45/min is above the expected reference range for a 3-year-old toddler and may indicate respiratory dysfunction or acute respiratory distress. It is essential for the nurse to report this finding promptly to the healthcare provider for further evaluation and intervention.

3. A patient taking isotretinoin (Accutane) for acne vulgaris. Which statement indicates that the patient teaching has been effective?

• A. I should use a reliable form of birth control.
• B. I will stop taking the drug if my skin is dry.
• C. It is important to increase intake of vitamin A.
• D. I do not need to use sunblock while taking Accutane.

Correct answer: A

Rationale: The correct answer is A. Isotretinoin is highly teratogenic, which means it can cause birth defects. Therefore, it is crucial for patients, especially females of childbearing potential, to use effective forms of birth control to prevent pregnancy while taking this medication. This is a key component of patient teaching to ensure the safe use of isotretinoin. Choice B is incorrect because discontinuing isotretinoin abruptly can lead to a flare-up of acne. Choice C is incorrect because increasing vitamin A intake can be harmful due to the risk of hypervitaminosis A. Choice D is incorrect because isotretinoin makes the skin more sensitive to sunlight, so sunblock is essential to prevent sunburn and skin damage.

4. Which food should be avoided by a child with acute glomerulonephritis to prevent hyperkalemia, as recommended by the nurse?

• A. Dairy products
• B. Whole-grain cereals
• C. Organ meats
• D. Bananas

Correct answer: D

Rationale: Bananas are rich in potassium, which can contribute to hyperkalemia in individuals with acute glomerulonephritis. It is essential to limit potassium intake to prevent further complications associated with high potassium levels in the blood.

5. Why is the specific gravity for infants lower than for older children?

• A. Infants have a greater body surface area.
• B. Infants have a higher basal metabolic rate.
• C. Infants have a greater percentage of body weight that is water.
• D. Infants' kidneys are less able to concentrate urine.

Correct answer: D

Rationale: The correct answer is D because infants' kidneys are less developed compared to older children, making them less efficient at concentrating urine. This results in a lower specific gravity in infants. The other choices do not directly explain why the specific gravity is lower in infants.
