Nursing Elites

1. 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.

2. A client is in need of hemodialysis for end-stage renal failure. The physician has inserted an AV fistula. Which of the following nursing interventions is appropriate when caring for this access site?

• A. Assess for clotting in fistula tubing
• B. Apply a dressing over the fistula site
• C. Assess for a bruit or thrill at the site of the fistula
• D. Assess circulation proximal to the fistula site

Correct answer: A

Rationale: When caring for an AV fistula used for hemodialysis, it is important to assess for a bruit (a humming sound) or thrill (a vibrating sensation) at the site of the fistula. These indicate proper blood flow through the fistula, ensuring it is patent and suitable for hemodialysis. Assessing for clotting in fistula tubing (Choice A) is not a routine nursing intervention for AV fistulas. Applying a dressing over the fistula site (Choice B) is not necessary as the site needs to be accessible for hemodialysis. Assessing circulation proximal to the fistula site (Choice D) is important but not specific to caring for the access site of an AV fistula.

3. The mother of a child with hepatitis A tells the home care nurse that she is concerned because the child's jaundice seems worse. What is the nurse's best response?

• A. You need to change the child's diet.
• B. The child probably is infectious again.
• C. The jaundice may worsen before it resolves.
• D. You need to call the primary health care provider.

Correct answer: C

Rationale: The best response for the nurse in this situation is to explain to the mother that jaundice may seem to worsen before it eventually gets better. This is a common occurrence in hepatitis A. Option A about changing the child's diet is irrelevant to the concern raised by the mother and not supported by evidence. Option B suggesting the child is infectious again is incorrect and may cause unnecessary alarm as jaundice does not indicate reinfection. Option D, advising the mother to call the primary health care provider, is premature as the nurse can first provide education and reassurance regarding the expected course of jaundice in hepatitis A.

4. The major difference between a grand mal and petit mal seizure is that a person with a grand mal seizure will have _______________ and the person with a petit mal seizure will not.

• A. convulsive movements
• B. sleep apnea
• C. atonic movements
• D. flaccidity

Correct answer: A

Rationale: The major difference between a grand mal and petit mal seizure is the presence or absence of convulsive movements. Grand mal seizures are characterized by convulsive movements, including jerking of limbs and loss of consciousness. In contrast, petit mal seizures, also known as absence seizures, typically involve brief episodes of staring or eye blinking without convulsive movements. Therefore, choice A, 'convulsive movements,' is the correct answer. Choices B, 'sleep apnea,' and D, 'flaccidity,' are incorrect as they are not associated with the characteristics of grand mal or petit mal seizures. Choice C, 'atonic movements,' is also incorrect as petit mal seizures do not involve atonic movements, but rather absence behaviors such as staring spells.

5. A 34-year-old female has recently been diagnosed with an autoimmune disease. She has also recently discovered that she is pregnant. Which of the following is the only immunoglobulin that will provide protection to the fetus in the womb?

• A. IgA
• B. IgD
• C. IgE
• D. IgG

Correct answer: D

Rationale: IgG is the only immunoglobulin that can cross the placental barrier, providing passive immunity to the fetus. About 70-80% of the immunoglobulins in the blood are IgG. Specific IgG antibodies are generated after an initial exposure to an antigen, offering long-term protection against microorganisms. IgG antibodies are critical for protecting the fetus as they can be rapidly reproduced upon re-exposure to the same antigen. IgA is primarily found in mucosal areas, IgD is involved in antigen recognition, and IgE is associated with allergic reactions, but they do not provide the same level of protection to the fetus as IgG.
