The parents of a 4-month-old infant tell the nurse that they are getting a microwave oven and will be able to heat the baby's formula faster. What should the nurse recommend?

Correct Answer: A

Rationale: The nurse should recommend never heating a bottle in a microwave oven. Microwaves do not heat liquids evenly, and there is a risk of creating hot spots in the formula, which can burn the baby's mouth and throat. It is safer to heat the formula by placing the bottle in warm water or using a bottle warmer to ensure uniform heating throughout.

Correct Answer: A

Rationale: Oxygen is not transported in blood plasma. Instead, it is transported bound to hemoglobin within red blood cells. Carbon dioxide, nutrients, and hormones are examples of substances that are transported in blood plasma. Oxygen binds to hemoglobin in the red blood cells as they pass through the lungs, while carbon dioxide is carried back to the lungs and expelled from the body through the respiratory system. Nutrients like glucose and amino acids are carried in the blood plasma to be delivered to various tissues for energy production and cellular processes. Hormones are chemical messengers that are released into the bloodstream by endocrine glands to regulate numerous physiological functions throughout the body.

Correct Answer: D

Rationale: In newborns, intramuscular phytonadione (vitamin K) is typically administered into the vastus lateralis muscle. This muscle is located on the front of the thigh and is a commonly used site for IM injections in infants due to its large muscle mass, accessibility, and low risk of hitting major nerves or blood vessels. The vastus lateralis muscle is considered a safe and effective site for administering medications to newborns.

Correct Answer: A

Rationale: The nurse should instruct the client to comply with the timing of antiviral medication around meals. Taking some antiviral medications with food can help reduce gastrointestinal side effects. Certain medications may be more effective when taken with food, while others may need to be taken on an empty stomach. It is essential for the client to follow the specific instructions given by their healthcare provider to ensure the optimal effectiveness of the antiviral medications.

Correct Answer: C

Rationale: Wilms tumor typically occurs in children aged 2-5 years and may be associated with congenital anomalies. It is not the same as neuroblastoma, and its prognosis is generally good with treatment.
