Nursing Elites

1. Which developmental behavior should the practical nurse identify as normal for a 6-month-old infant?

• A. Rolls over completely.
• B. Creeps on all fours.
• C. Pulls self to a standing position.
• D. Assumes a sitting position independently.

Correct answer: A

Rationale: The correct answer is A: 'Rolls over completely.' By 6 months of age, infants typically achieve the milestone of rolling over completely. This ability demonstrates increasing strength and coordination. Creeping on all fours, pulling self to a standing position, and assuming a sitting position independently are skills that are usually developed at later stages of infancy. Creeping usually occurs around 9-10 months, pulling self to a standing position around 9-12 months, and assuming a sitting position independently around 8 months. Therefore, at 6 months, rolling over completely is the most expected developmental behavior.

2. What information should the nurse provide to parents of a 3-year-old boy with Duchenne muscular dystrophy who inquire about the disease and future children?

• A. This is an inherited X-linked recessive disorder, which primarily affects male children in the family
• B. The striated muscle groups of males can be impacted by a lack of the protein dystrophin in their mothers
• C. The male infant had a viral infection that went unnoticed and untreated so muscle damage was incurred
• D. Birth trauma with a breech vaginal birth causes damage to the spinal cord, thus weakening the muscles

Correct answer: A

Rationale: Duchenne muscular dystrophy is an X-linked recessive disorder caused by mutations in the DMD gene on the X chromosome. This disorder primarily affects males because they have one X chromosome, inherited from their mothers, who may be carriers of the mutated gene. Females have two X chromosomes, providing a protective effect as the normal gene on one X chromosome can compensate for the mutated gene on the other. Therefore, the nurse should explain to the parents that Duchenne muscular dystrophy is an inherited X-linked recessive disorder, which is why their son has the disease and why there is a risk of passing it on to future sons. Choice B is incorrect as it inaccurately implies that the lack of dystrophin in mothers impacts their sons' muscle groups. Choice C is incorrect as it suggests a viral infection caused the muscle damage, which is not the case with Duchenne muscular dystrophy. Choice D is incorrect as it attributes the muscle weakness to birth trauma instead of the genetic nature of the disorder.

3. A child who is admitted to the hospital with anemia is anxious, fearful, and hyperventilating. The nurse anticipates the child developing which acid-base imbalance?

• A. Metabolic acidosis
• B. Respiratory acidosis
• C. Respiratory alkalosis
• D. Metabolic alkalosis

Correct answer: C

Rationale: In this scenario, the child is hyperventilating, which leads to excessive loss of carbon dioxide. This loss of carbon dioxide causes respiratory alkalosis due to a decrease in the partial pressure of carbon dioxide in the blood. Therefore, the correct answer is respiratory alkalosis. Choices A, B, and D are incorrect. Metabolic acidosis is characterized by a decrease in pH and bicarbonate levels due to conditions like kidney disease. Respiratory acidosis is caused by retention of carbon dioxide, leading to an increase in the partial pressure of carbon dioxide. Metabolic alkalosis results from a loss of acid or an increase in bicarbonate levels.

4. The practical nurse is caring for a child who was admitted for treatment of seizures. Which intervention should the nurse implement to help prevent injury from a seizure?

• A. Have a padded tongue depressor at the bedside.
• B. Keep the side rails padded and in an upright position.
• C. Place a padded helmet on the child’s head.
• D. Restrain the child during the seizure activity.

Correct answer: B

Rationale: The correct intervention to help prevent injury during a seizure is to keep the side rails padded and in an upright position. This measure helps to ensure the child's safety by preventing falls or accidental injuries. Using a padded tongue depressor or restraining the child can potentially cause harm and are not recommended. Placing a padded helmet is not a standard intervention for seizure safety in this scenario.

5. What action should the nurse implement after the infusion is complete for a 16-year-old with acute myelocytic leukemia receiving chemotherapy via an implanted medication port at the outpatient oncology clinic?

• A. Administer Zofran
• B. Obtain blood samples for RBCs, WBCs, and platelets
• C. Flush the mediport with saline and heparin solution
• D. Initiate an infusion of normal saline

Correct answer: C

Rationale: After completing the chemotherapy infusion via the implanted medication port, the nurse should flush the mediport with saline and heparin solution. This action helps prevent clot formation in the port, ensuring its patency for future use and reducing the risk of complications associated with catheter occlusion. Administering Zofran (Choice A) is used for managing chemotherapy-induced nausea and vomiting, not for post-infusion care. Obtaining blood samples for RBCs, WBCs, and platelets (Choice B) is important for monitoring the patient's blood count but is not the immediate post-infusion priority. Initiating an infusion of normal saline (Choice D) is not necessary after completing the chemotherapy infusion.
