1. 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.
2. A physician suspects a patient may have pancreatitis. Which of the following tests would be most appropriate to diagnose this condition?
- A. CK and Troponin
- B. BUN and Creatinine
- C. Amylase and Lipase
- D. HDL and LDL Cholesterol Levels
Correct answer: C
Rationale: To diagnose pancreatitis, testing amylase and lipase levels is crucial. Amylase and lipase are enzymes produced by the pancreas that help digest carbohydrates and lipids. In pancreatitis, these enzymes are released in high amounts into the bloodstream due to pancreatic inflammation or damage. Elevated levels of amylase and lipase in blood tests strongly indicate pancreatitis. Choice A, CK and Troponin, are cardiac markers used in diagnosing heart conditions like myocardial infarction, not pancreatitis. Choice B, BUN and Creatinine, are kidney function tests, not specific to pancreatitis. Choice D, HDL and LDL Cholesterol Levels, are lipid profile tests used to assess cardiovascular health, not for diagnosing pancreatitis.
3. A patient is deciding whether they should take the live influenza vaccine (nasal spray) or the inactivated influenza vaccine (shot). The nurse reviews the client's history. Which condition would NOT contraindicate the nasal (live vaccine) route of administration?
- A. The patient takes long-term corticosteroids
- B. The patient is not feeling well today
- C. The patient is 55 years old
- D. The patient has young children
Correct answer: D
Rationale: The correct answer is that the patient has young children. Having young children is not a contraindication for the live influenza vaccine unless the children are immunocompromised, which is not mentioned. Choice A, the patient taking long-term corticosteroids, is a contraindication for the live vaccine due to potential immunosuppression. Choice B, the patient not feeling well today, is a general precaution for vaccination and not a contraindication specific to the live influenza vaccine. Choice C, the patient being 55 years old, is not a contraindication for the live vaccine unless there are other specific medical conditions present.
4. Which client is at highest risk for developing a pressure ulcer?
- A. 23 year-old in traction for fractured femur
- B. 72 year-old with peripheral vascular disease, who is unable to walk without assistance
- C. 75 year-old with left sided paresthesia and is incontinent of urine and stool
- D. 30 year-old who is comatose following a ruptured aneurysm
Correct answer: C
Rationale: Risk factors for pressure ulcers include: immobility, absence of sensation, decreased LOC, poor nutrition and hydration, skin moisture, incontinence, increased age, decreased immune response. This client has the greatest number of risk factors.
5. Which of the following medications taken by the patient is least likely to cause urine discoloration?
- A. Sulfasalazine
- B. Levodopa
- C. Phenolphthalein
- D. Aspirin
Correct answer: D
Rationale: The correct answer is Aspirin. Aspirin is not known to cause urine discoloration. Sulfasalazine is associated with causing orange-yellow discoloration of urine. Levodopa can cause darkening of urine to a brown or black color. Phenolphthalein has been linked to pink or red discoloration of urine. Therefore, among the options provided, Aspirin is the medication least likely to cause urine discoloration.
