Nursing Elites

1. 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.

2. A client in the ICU has been intubated and placed on a ventilator. The physician orders synchronous intermittent mandatory ventilation (SIMV). Which statement best describes the work of this mode of ventilation?

• A. The ventilator delivers a set rate and tidal volume regardless of whether the client is attempting to breathe
• B. The ventilator coordinates delivered breaths with the client's respiratory efforts
• C. The ventilator provides a supplemental breath for every third breath of the client
• D. The ventilator provides breaths during the expiratory phase of the client's respirations

Correct answer: B

Rationale: Synchronous intermittent mandatory ventilation (SIMV) is a ventilation mode that coordinates delivered breaths with the client's own respiratory efforts. This mode allows the client to initiate breaths, with the ventilator providing preset breaths at a controlled rate and volume. Option A is incorrect because in SIMV, the ventilator syncs with the client's respiratory efforts. Option C is incorrect as it does not accurately depict the way SIMV works. Option D is also incorrect as SIMV does not specifically provide breaths during the expiratory phase of the client's respirations. Therefore, the correct answer is B, where the ventilator coordinates breath delivery with the client's breathing efforts.

3. The nurse provides home care instructions to the parents of a child with celiac disease. The nurse should teach the parents to include which food item in the child's diet?

• A. Rice
• B. Oatmeal
• C. Rye toast
• D. White bread

Correct answer: A

Rationale: In celiac disease, individuals are intolerant to gluten found in wheat, barley, rye, and oats. Therefore, it is crucial to eliminate these grains from the diet. Rice, corn, or millet are safe alternatives for individuals with celiac disease. Oatmeal is generally avoided unless specifically labeled as gluten-free due to possible cross-contamination. Rye toast and white bread contain gluten and should be avoided in celiac disease. Vitamin supplements may also be necessary to address deficiencies caused by dietary restrictions.

4. The healthcare professional calculates the IV flow rate for a patient receiving an antibiotic. The patient is to receive 100mL of the antibiotic over 30 minutes. The IV infusion set has a drop factor of 10 drops per milliliter. How many drops per minute should the healthcare professional set the IV to deliver?

• A. 11
• B. 19
• C. 26
• D. 33

Correct answer: D

Rationale: To determine the drops per minute for the IV flow rate, you can use the formula: Drops Per Minute = (Milliliters to be infused x Drop Factor) / Time in Minutes. Substituting the given values, you get 100 mL x 10 drops/mL / 30 minutes = 33 drops per minute. Therefore, the correct answer is 33, as the healthcare professional should set the IV to deliver 33 drops per minute to infuse the antibiotic correctly. Choices A, B, and C are incorrect as they do not match the calculated drops per minute based on the provided values.

5. 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.
