Calcium carbonate is given with meals to a child with chronic renal disease. What is the purpose of administering calcium carbonate?

Correct Answer: B

Rationale: In chronic renal disease, the kidneys are not functioning properly, leading to an accumulation of phosphorus in the body. High levels of phosphorus can be harmful and contribute to bone and mineral disorders. Calcium carbonate is often given with meals to bind phosphorus in the gut and prevent its absorption. By binding with phosphorus, calcium carbonate helps lower the levels of phosphorus in the blood, thereby managing complications associated with chronic renal disease, such as renal osteodystrophy. It is an essential part of the treatment plan for patients with chronic kidney disease to help maintain appropriate phosphorus balance in the body and prevent further complications.

Correct Answer: B

Rationale: Developmental dysplasia of the hip (DDH) is a condition where the hip joint does not develop normally. It is important to detect DDH early in infants as it can lead to long-term hip problems. One of the key physical exam findings that may suggest DDH is unequal knee heights when the infant's legs are flexed. This is known as the Galeazzi sign, and it can indicate hip dysplasia or dislocation. Therefore, if a nurse observes this finding during an assessment of a 3-month-old infant, it would warrant recommending an ultrasound to further evaluate for possible DDH. Bilateral plantar flexion, bilateral polydactyly, and a positive Babinski test are not typically associated with DDH.

Correct Answer: A

Rationale: The highest priority nursing diagnosis in this scenario is Deficient fluid volume related to osmotic diuresis. The client's serum glucose level of 618mg/dl indicates severe hyperglycemia, which is likely causing osmotic diuresis leading to fluid volume deficit. The client's hot, dry skin, along with a heart rate of 116 beats/min, and blood pressure of 108/70mmHg are symptoms of dehydration due to fluid loss. If left untreated, deficient fluid volume can lead to serious complications such as hypovolemic shock. Therefore, addressing the fluid volume deficit is essential to stabilize the client's condition before other nursing diagnoses are addressed.

Correct Answer: D

Rationale: The correct client statement indicating effective teaching about parenteral vitamin B12 therapy for pernicious anemia is, "I will receive parenteral vitamin B12 therapy for the rest of my life." Pernicious anemia is a condition in which the body cannot absorb enough vitamin B12 from food due to a lack of intrinsic factor, a protein produced in the stomach. As a result, lifelong B12 supplementation is necessary to maintain adequate levels of the vitamin. Monthly injections are typically recommended for life to ensure proper B12 levels and prevent complications associated with the deficiency.

Correct Answer: C

Rationale: Bacon contains the highest kilocalories among the food choices provided. Bacon is high in fat, with approximately 42 kilocalories per slice (8 grams) compared to other options like an apple (52 kilocalories), chicken (231 kilocalories), and bread (79 kilocalories). The high fat content in bacon contributes to its higher caloric value compared to the other choices listed. As such, bacon is the food choice with the highest kilocalorie content in this selection.
