The nurse in the newborn nursery is planning for the admission of a large for gestational age (LGA) infant. In preparing to care for this infant, the nurse should obtain equipment to perform which diagnostic test?
- A. Serum insulin level
- B. Heel stick blood glucose
- C. Rh and ABO blood typing
- D. Indirect and direct bilirubin levels
Correct Answer: B
Rationale: After birth, the most common problem in the LGA infant is hypoglycemia, especially if the mother is diabetic. At delivery when the umbilical cord is clamped and cut, maternal blood glucose supply is lost. The newborn continues to produce large amounts of insulin, which depletes the infant's blood glucose within the first hours after birth.

The nurse is teaching a pregnant client about prenatal nutritional needs. The nurse should include which information in the client's teaching plan?
- A. All mothers are at high risk for nutritional deficiencies.
- B. Calcium intake is not necessary until the third trimester.
- C. Iron supplements are not necessary unless the mother has iron deficiency anemia.
- D. The nutritional status of the mother significantly influences fetal growth and development.
Correct Answer: D
Rationale: Poor nutrition during pregnancy can negatively influence fetal growth and development. Although pregnancy poses some nutritional risk for the mother, not all clients are at high risk. Calcium intake is critical during the third trimester but must be increased from the onset of pregnancy. Intake of dietary iron is insufficient for the majority of pregnant women, and iron supplements are routinely prescribed.
The nurse provides information to a client diagnosed with gastroesophageal reflux disease (GERD). What information should the nurse include when discussing foods that contribute to decreased lower esophageal sphincter (LES) pressure and thus worsen the condition? Select all that apply.
- A. Alcohol
- B. Fatty foods
- C. Citrus fruits
- D. Baked potatoes
- E. Caffeinated beverages
- F. Tomatoes and tomato products
Correct Answer: A,B,C,E,F
Rationale: GERD occurs as a result of the backward flow (reflux) of gastrointestinal contents into the esophagus. The most common cause of GERD is inappropriate relaxation of the LES, which allows the reflux of gastric contents into the esophagus and exposes the esophageal mucosa to gastric contents. Factors that influence the tone and contractility of the LES and lower LES pressure include alcohol; fatty foods; citrus fruits; caffeinated beverages such as coffee, tea, and cola; tomatoes and tomato products; chocolate; nicotine in cigarette smoke; calcium channel blockers; nitrates; anticholinergics; high levels of estrogen and progesterone; peppermint and spearmint; and nasogastric tube placement. Baked potatoes would not contribute to worsening the problem.
A client with a diagnosis of diabetes mellitus has a blood glucose level of 644 mg/dL (36.8 mmol/L). The nurse interprets that this client is at risk of developing which type of acid-base imbalance?
- A. Metabolic acidosis
- B. Metabolic alkalosis
- C. Respiratory acidosis
- D. Respiratory alkalosis
Correct Answer: A
Rationale: Diabetes mellitus can lead to metabolic acidosis. When the body does not have sufficient circulating insulin, the blood glucose level rises. At the same time, the cells of the body use all available glucose. The body then breaks down glycogen and fat for fuel. The by-products of fat metabolism are acidotic and can lead to the condition known as diabetic ketoacidosis. Options 2, 3, and 4 are incorrect.
The client states that he has smoked three-fourths of a pack per day over the last 10 years. The nurse calculates that the client has a smoking history of how many pack-years?
Correct Answer: 7.5
Rationale: The standard method for quantifying smoking history is to multiply the number of packs smoked per day by the number of years of smoking. The number is recorded as the number of pack-years. The calculation for the number of pack-years for the client who has smoked three-fourths of a pack per day for 10 years is 0.75 pack × 10 years = 7.5 pack-years.
On assessment of a newborn being admitted to the nursery, the nurse palpates the anterior fontanel and notes that it feels soft. The nurse determines that this finding indicates which condition?
- A. Dehydration
- B. A normal finding
- C. Increased intracranial pressure
- D. Decreased intracranial pressure
Correct Answer: B
Rationale: The anterior fontanel is normally 2 to 3 cm in width, 3 to 4 cm in length, and diamond-like in shape. It can be described as soft, which is normal, or full and bulging, which could indicate increased intracranial pressure. Conversely a depressed fontanel could mean that the infant is dehydrated.
