1. Which of the following conditions is a contraindication for performing a diagnostic peritoneal lavage?

• A. A client who is 9 weeks pregnant
• B. A client with a femur fracture
• C. A morbidly obese client
• D. A client with hypertension

Correct answer: C

Rationale: Diagnostic peritoneal lavage is contraindicated in morbidly obese clients due to several reasons. Excess body fat in morbidly obese individuals makes it challenging to locate essential landmarks required for the procedure. Additionally, the equipment utilized for the lavage may not be sized appropriately to accommodate an obese individual. Furthermore, morbid obesity places undue stress on the cardiovascular and respiratory systems, increasing the risk of complications when administering anesthetic agents during the procedure. Therefore, performing a diagnostic peritoneal lavage on a morbidly obese client is not recommended. Choice A, a client who is 9 weeks pregnant, is not a contraindication for diagnostic peritoneal lavage. Pregnancy status alone does not preclude the procedure unless there are specific maternal or fetal concerns. Choice B, a client with a femur fracture, is not a contraindication for diagnostic peritoneal lavage. The presence of a femur fracture does not typically affect the ability to perform this diagnostic procedure. Choice D, a client with hypertension, is not a contraindication for diagnostic peritoneal lavage. Hypertension, while a consideration for anesthesia and surgery, does not directly impact the feasibility of performing a diagnostic peritoneal lavage.

2. In a pediatric clinic, a nurse is assessing a child recently diagnosed with cystic fibrosis. Which of the following later findings of this disease would the nurse not expect to see at this time?

• A. Positive sweat test
• B. Bulky greasy stools
• C. Moist, productive cough
• D. Meconium ileus

Correct answer: C

Rationale: In a child newly diagnosed with cystic fibrosis (CF), noisy respirations and a dry, non-productive cough are typically the first respiratory signs to appear. The other options, including a positive sweat test, bulky greasy stools, and meconium ileus, are among the earliest findings of CF. CF is a genetic condition that affects the production of mucus, sweat, saliva, and digestive juices. Due to a defective gene, these secretions become thick and sticky instead of thin and slippery, leading to blockages in various passageways, especially in the pancreas and lungs. Respiratory failure is a severe consequence of CF, making it crucial to monitor respiratory symptoms closely in affected individuals. Therefore, a moist, productive cough would not be an expected finding in a newly diagnosed child with CF.

3. While caring for a patient with respiratory disease, the nurse observes that the patient's SpO2 drops from 93% to 88% while the patient is ambulating in the hallway. What is the priority action of the nurse?

• A. Notify the healthcare provider
• B. Document the response to exercise
• C. Administer the PRN supplemental O2
• D. Encourage the patient to pace activity

Correct answer: C

Rationale: The drop in SpO2 to 88% indicates that the patient is hypoxemic and needs supplemental oxygen when exercising. Administering PRN supplemental oxygen is the priority action to correct the hypoxemia and ensure adequate oxygenation during activity. Notifying the healthcare provider can be done after stabilizing the patient's oxygen levels. Documenting the response to exercise is important but secondary to addressing the immediate hypoxemia. Encouraging the patient to pace activity is not sufficient to address the acute drop in SpO2 and provide the necessary oxygen support.

4. A patient has been diagnosed with acute gastritis in a clinic. Which of the following medications would be contraindicated for this patient?

• A. Naproxen sodium (Naprosyn)
• B. Calcium carbonate
• C. Clarithromycin (Biaxin)
• D. Furosemide (Lasix)

Correct answer: A

Rationale: Naproxen sodium is a nonsteroidal anti-inflammatory drug that can cause inflammation of the upper GI tract. For this reason, it is contraindicated in a patient with gastritis. Gastritis involves inflammation of the stomach lining, and medications like Naproxen can exacerbate this condition. Calcium carbonate is an antacid that can help neutralize stomach acid and may actually provide relief for gastritis symptoms. Clarithromycin is an antibiotic used to treat H. pylori infection, a common cause of gastritis. Furosemide is a loop diuretic used to treat conditions like edema and hypertension, not directly contraindicated in gastritis.

5. 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.
