Nursing Elites

1. The nurse is caring for a client with a serum potassium level of 3.5 mEq/L. The client is placed on a cardiac monitor and receives 40 mEq potassium chloride in 1000 ml of 5% dextrose in water IV. Which of the following EKG patterns indicates to the nurse that the infusions should be discontinued?

• A. Narrowed QRS complex
• B. Shortened "PR"? interval
• C. Tall peaked "T"? waves
• D. Prominent "U"? waves

Correct answer: C

Rationale: A tall peaked T wave is a characteristic EKG pattern associated with hyperkalemia. Hyperkalemia refers to high levels of potassium in the blood, which can lead to cardiac arrhythmias and other serious complications. Tall peaked T waves are a red flag for potential cardiac issues and can indicate the need to discontinue potassium infusions. The other choices, such as narrowed QRS complex, shortened "PR"? interval, and prominent "U"? waves, are not typically associated with hyperkalemia. Therefore, recognizing tall peaked T waves is crucial for the nurse to take prompt action in managing the client's condition.

2. The parents of a 2-year-old child who had an orchiopexy to correct cryptorchidism are provided with discharge instructions by the nurse. Which statement by the parents indicates the need for further instruction?

• A. I'll check his temperature.
• B. I'll give him medication so he'll be comfortable.
• C. I'll check his voiding to be sure there's no problem.
• D. I'll let him decide when to return to his play activities.

Correct answer: D

Rationale: Cryptorchidism is a condition where one or both testes fail to descend into the scrotal sac. Orchiopexy, a surgical correction, may be required. After surgery, it is crucial to restrict vigorous activities for 2 weeks to promote healing and prevent injury. Allowing the child to decide when to return to play activities may lead to delayed healing and increased risk of injury, as 2-year-olds typically want to be active. Checking the child's temperature, administering analgesics as needed, and monitoring urine output are important postoperative care measures to ensure recovery and detect complications early. Therefore, the statement indicating the need for further instruction is the one related to letting the child decide when to resume play activities.

3. The mother of a child who had a cleft palate repair 4 days ago is receiving home care instructions. Which statement by the mother indicates the need for further instruction?

• A. ''I will use a short nipple on the bottle.''
• B. ''I should avoid using straws for drinking.''
• C. ''I can give my child the pacifier in 2 weeks.''
• D. ''I may give my baby food mixed with water.''

Correct answer: B

Rationale: The correct answer is ''I should avoid using straws for drinking.'' After a cleft palate repair, the child should avoid straws, pacifiers, spoons, and fingers near the mouth for 7 to 10 days to prevent injury to the surgical site. Allowing the child to use a straw can create negative pressure in the mouth, potentially disrupting the healing process. The other options are appropriate postoperative instructions for a child who had a cleft palate repair and do not pose a risk to the surgical site.

4. Which finding would necessitate an immediate change in the therapeutic plan for a patient with grade 2 hepatic encephalopathy?

• A. Weight loss of 2 lb (1 kg)
• B. Positive urine pregnancy test
• C. Hemoglobin level of 10.4 g/dL
• D. Complaints of nausea and anorexia

Correct answer: B

Rationale: A positive urine pregnancy test would require an immediate change in the therapeutic plan for a patient with grade 2 hepatic encephalopathy due to the teratogenic effects of ribavirin. Ribavirin needs to be discontinued immediately to prevent harm to the fetus. The other options, weight loss, hemoglobin level, and complaints of nausea and anorexia, are common adverse effects of the prescribed regimen and may necessitate interventions such as patient education or supportive care, but they would not mandate an immediate cessation of therapy as in the case of a positive pregnancy test.

5. A child presents to the emergency department with colicky abdominal pain in the lower right quadrant. What disorder is suspected based on these symptoms?

• A. Peritonitis
• B. Appendicitis
• C. Intussusception
• D. Hirschsprung's disease

Correct answer: B

Rationale: The child's presentation of colicky abdominal pain in the lower right quadrant is classic for appendicitis. Appendicitis typically presents with localized pain that starts near the umbilicus and then shifts to the right lower quadrant. Peritonitis, on the other hand, is characterized by diffuse abdominal pain, tenderness, and guarding, usually resulting from organ perforation or intestinal obstruction. Intussusception is associated with acute, severe abdominal pain and currant jelly-like stools due to intestinal telescoping. Hirschsprung's disease, which lacks ganglion cells in the colon, manifests with symptoms like constipation, abdominal distension, and foul-smelling, ribbon-like stools.
