Nursing Elites

1. A new mother asks the nurse, 'I was told that my infant received my antibodies during pregnancy. Does that mean that my infant is protected against infections?' Which statement should the nurse make in response to the mother?

• A. The immune system of an infant is immature, and the infant is at risk for infection.
• B. The transfer of your antibodies protects your infant until the infant is 12 months old.
• C. Yes, your infant is protected from all infections.
• D. If you breastfeed, your infant is protected from infection.

Correct answer: A

Rationale: The transplacental transfer of maternal antibodies supplements the infant's weak response to infection until approximately 3 to 4 months of age. While the infant starts producing immunoglobulin (Ig) soon after birth, it only reaches about 60% of the adult IgG level, 75% of the adult IgM level, and 20% of the adult IgA level by 1 year of age. Breast milk provides additional IgA protection. Although the immune system matures during infancy, full protection against infections is not achieved until early childhood, putting the infant at risk for infections. Choice B is incorrect because maternal antibody protection typically lasts around 3 to 4 months, not until the infant is 12 months old. Choice C is incorrect as infants are not shielded from all infections due to their immature immune system. Choice D is incorrect because while breastfeeding offers extra protection, it does not guarantee complete immunity against infections.

2. The nurse is teaching a client about sleep and gives background information on normal sleep patterns. Which of the following substances promotes sleep?

• A. serotonin
• B. cortisol
• C. alcohol
• D. narcotics

Correct answer: A

Rationale: Serotonin is a substance found in the body that promotes sleep. It plays a role in the synthesis of a hypnogenic factor that directly induces sleep. Cortisol is a stress hormone that can disrupt sleep patterns. Alcohol can disrupt REM sleep and negatively impact sleep quality. Narcotics, like alcohol, can interfere with sleep architecture and lead to poor quality sleep. Therefore, the correct answer is serotonin as it is associated with promoting sleep, while the other substances listed can have negative effects on sleep patterns.

3. Which of the following conditions has a severe complication of respiratory failure?

• A. Bell's palsy
• B. Guillain-Barré syndrome
• C. Trigeminal neuralgia
• D. Tetanus

Correct answer: B

Rationale: Guillain-Barré syndrome is characterized by a severe complication of respiratory failure due to the involvement of the peripheral nerves that control breathing. While Bell's palsy, trigeminal neuralgia, and tetanus are also conditions affecting peripheral nerves, they do not typically lead to respiratory failure like Guillain-Barré syndrome. Bell's palsy causes facial muscle weakness, trigeminal neuralgia results in severe facial pain, and tetanus leads to muscle stiffness and spasms, but none of these conditions directly involve respiratory failure.

4. A nurse is watching as a new nurse employee administers an intramuscular (IM) injection in a client's deltoid muscle. The nurse determines that the new employee is performing the procedure correctly if the new employee uses which technique?

• A. Administers the injection 2 inches below the acromion process
• B. Positions the client with the deltoid muscle exposed
• C. Administers the injection in the thigh
• D. Places the client in the Sims position

Correct answer: A

Rationale: When administering an intramuscular injection in the deltoid muscle, the correct technique involves administering the injection 2 inches below the acromion process, which is the bony structure on top of the shoulder blade. This location ensures safe and effective administration. Administering the injection in the thigh (vastus lateralis or rectus femoris muscle) is not appropriate for a deltoid injection as the deltoid muscle is located in the upper arm. The Sims position is not the correct position for a deltoid muscle injection. While positioning the client with the deltoid muscle exposed allows for proper access and visualization, the critical aspect for a correct deltoid injection is the accurate injection site, 2 inches below the acromion process.

5. Following a classic cholecystectomy resection for multiple stones, the PACU nurse observes serosanguinous drainage on the dressing. The most appropriate intervention is to:

• A. notify the physician of the drainage.
• B. change the dressing.
• C. reinforce the dressing.
• D. apply an abdominal binder

Correct answer: C

Rationale: Serosanguinous drainage is expected after a classic cholecystectomy resection. The appropriate intervention is to reinforce the dressing to maintain pressure and promote clot formation. Changing the dressing prematurely increases the risk of infection as it disturbs the wound. Applying an abdominal binder is not indicated as it can interfere with visualizing the dressing and assessing for any signs of bleeding or infection. Notifying the physician is not necessary at this point unless there are signs of excessive bleeding or other concerning symptoms.
