Nursing Elites

1. A couple asks the nurse about risks of several birth control methods. What is the most appropriate response by the nurse?

• A. Norplant is safe and can be easily removed.
• B. Oral contraceptives should not be used by smokers.
• C. Depo-Provera is convenient with few side effects.
• D. The IUD provides protection against pregnancy and infection.

Correct answer: B

Rationale: The correct answer is that oral contraceptives should not be used by smokers. The use of oral contraceptives in a woman who smokes increases the risk of cardiovascular problems, such as thromboembolic disorders. This is due to the combined effect of smoking and hormonal contraceptives. Choices A, C, and D are incorrect because they do not address the specific risk associated with smoking and oral contraceptives. Norplant's safety and ease of removal, Depo-Provera's convenience with few side effects, and the IUD's protection against pregnancy and infection are important points but not directly related to the increased risks for smokers using oral contraceptives.

2. A patient asks the nurse why they must have a heparin injection. What is the nurse's best response?

• A. Heparin will dissolve clots that you have.
• B. Heparin will reduce the platelets that make your blood clot.
• C. Heparin will work better than warfarin.
• D. Heparin will prevent new clots from developing.

Correct answer: D

Rationale: The correct answer is D: 'Heparin will prevent new clots from developing.' Heparin is an anticoagulant medication that helps prevent the formation of new blood clots. It does not dissolve existing clots (choice A), reduce platelets (choice B), or necessarily work 'better' than warfarin (choice C) but rather functions differently. The primary action of heparin is to prevent the development of new clots, especially in conditions where clot formation is a concern.

3. A patient with a history of diabetes mellitus is on the second postoperative day following cholecystectomy. She has complained of nausea and isn't able to eat solid foods. The nurse enters the room to find the patient confused and shaky. Which of the following is the most likely explanation for the patient's symptoms?

• A. Anesthesia reaction
• B. Hyperglycemia
• C. Hypoglycemia
• D. Diabetic ketoacidosis

Correct answer: C

Rationale: In a postoperative diabetic patient who is unable to eat solid foods, the likely cause of symptoms such as confusion and shakiness is hypoglycemia. Confusion and shakiness are common manifestations of hypoglycemia. Insufficient glucose supply to the brain (neuroglycopenia) can lead to confusion, difficulty with concentration, irritability, hallucinations, focal impairments like hemiplegia, and, in severe cases, coma and death. Anesthesia reaction (Choice A) is less likely in this scenario as the patient is already on the second postoperative day. Hyperglycemia (Choice B) is unlikely given the patient's symptoms and history of not eating. Diabetic ketoacidosis (Choice D) typically presents with hyperglycemia, ketosis, and metabolic acidosis, which are not consistent with the patient's current symptoms of confusion and shakiness.

4. A child weighing 30 kg arrives at the clinic with diffuse itching as the result of an allergic reaction to an insect bite. Diphenhydramine (Benadryl) 25 mg 3 times a day is prescribed. The correct pediatric dose is 5 mg/kg/day. Which of the following best describes the prescribed drug dose?

• A. It is the correct dose
• B. The dose is too low
• C. The dose is too high
• D. The dose should be increased or decreased, depending on the symptoms

Correct answer: B

Rationale: The correct pediatric dose of diphenhydramine is 5 mg/kg/day. This child weighs 30 kg, so the calculated dose would be 5 mg/kg x 30 kg = 150 mg/day. Since the prescription is for 25 mg 3 times a day, the total daily dose is 25 mg x 3 = 75 mg/day, which is lower than the calculated dose of 150 mg/day. Therefore, the prescribed dose of 25 mg 3 times a day is too low for this child. The dose should be adjusted to meet the correct dosage of 150 mg/day, which would be 50 mg 3 times a day. It is important not to titrate the dosage based on symptoms without consulting a physician, as this can lead to inappropriate medication administration.

5. When caring for an asthmatic patient with an early-phase reaction, which of the following is indicative of an early-phase reaction?

• A. Rapid bronchospasms
• B. Inflammatory epithelial lesions
• C. Increased secretions
• D. Increased mucosal edema

Correct answer: A

Rationale: Rapid bronchospasms are a symptom of an early-phase reaction in an asthmatic patient. During the early phase, bronchospasms occur due to immediate hypersensitivity reactions. Inflammatory epithelial lesions, increased secretions, and increased mucosal edema are typically seen in late-phase reactions as part of the inflammatory response that occurs later. Therefore, rapid bronchospasms are most indicative of an early-phase reaction.
