Nursing Elites

1. 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.

2. A woman in her third trimester complains of severe heartburn. What is appropriate teaching by the nurse to help the woman alleviate these symptoms?

• A. Drink small amounts of liquids frequently
• B. Eat the evening meal at least 2-3 hours before bedtime
• C. Take sodium bicarbonate after each meal
• D. Sleep with head propped on several pillows

Correct answer: D

Rationale: During the third trimester, many women experience heartburn due to the pressure of the growing uterus on the stomach. Elevating the head while sleeping can help prevent gastric contents from refluxing back into the esophagus, thus reducing heartburn symptoms. Drinking small amounts of liquids frequently may exacerbate heartburn by increasing stomach distension. Eating the evening meal just before retiring can also worsen heartburn symptoms as lying down shortly after eating can promote reflux. Taking sodium bicarbonate after each meal is not recommended as it can disrupt the body's natural pH balance and lead to other complications.

3. A client complained of nausea, a metallic taste in her mouth, and fine hand tremors 2 hours after her first dose of lithium carbonate (Lithane). What is the nurse's best explanation of these findings?

• A. These side effects are common and should subside in a few days.
• B. The client is probably having an allergic reaction and should discontinue the drug.
• C. Taking the lithium on an empty stomach should decrease these symptoms.
• D. Decreasing dietary intake of sodium and fluids should minimize the side effects.

Correct answer: A

Rationale: The correct answer is, 'These side effects are common and should subside in a few days.' Nausea, metallic taste, and fine hand tremors are common side effects of lithium carbonate (Lithane) and typically diminish within a few days as the body adjusts to the medication. Option B is incorrect because these symptoms are not indicative of an allergic reaction. Option C is incorrect as taking lithium on an empty stomach does not directly address or decrease these specific side effects. Option D is also incorrect as reducing sodium and fluid intake is not the recommended approach to managing these particular side effects of lithium.

4. The nurse caring for Mrs. J is prepared to suction her endotracheal tube. Which of the following interventions will reduce hypoxia during this procedure?

• A. Hyperoxygenate Mrs. J for up to 60 seconds prior to starting
• B. Administer 15 mL of sterile fluid into the tube prior to suctioning
• C. Suction for no longer than 30 seconds at a time
• D. Wait 30 seconds after suctioning before attempting again

Correct answer: A

Rationale: Before suctioning a client's endotracheal tube, it is essential to hyperoxygenate the client for approximately 30 to 60 seconds. Hyperoxygenation helps increase oxygen delivery to the tissues, reducing the risk of hypoxia during and after the suctioning procedure. Administering fluid into the tube before suctioning (Choice B) is unnecessary and can lead to complications. Suctioning for no longer than 30 seconds at a time (Choice C) is a general guideline but does not specifically address reducing hypoxia. Waiting 30 seconds after suctioning before attempting again (Choice D) may lead to inadequate oxygenation and potential hypoxia, making it less effective in preventing this complication compared to hyperoxygenation prior to suctioning.

5. Following mitral valve replacement surgery, a client develops PVCs. The healthcare provider orders a bolus of Lidocaine followed by a continuous Lidocaine infusion at a rate of 2 mg/minute. The IV solution contains 2 grams of Lidocaine in 500 mL of D5W. The infusion pump delivers 60 microdrops/mL. What rate would deliver 4 mg of Lidocaine per minute?

• A. 60 microdrops/minute
• B. 20 microdrops/minute
• C. 30 microdrops/minute
• D. 40 microdrops/minute

Correct answer: A

Rationale: To calculate the rate needed to deliver 4 mg/minute of Lidocaine, first, convert 2 grams to milligrams: 2 grams = 2000 mg. Then, set up a ratio between the total amount of Lidocaine (2000 mg) and the total volume of IV solution (500 mL): 2000 mg / 500 mL = 4 mg / x mL. Solving for x, x = 1 mL. Since the infusion pump delivers 60 microdrops per mL, multiplying by 60 microdrops/mL gives the correct rate of 60 microdrops/minute. This rate ensures the desired 4 mg of Lidocaine is delivered per minute. Choices B, C, and D are incorrect as they do not align with the accurate calculation based on the provided information.
