The infant with congestive heart failure (CHF) has a need for:

Correct Answer: D

Rationale: Correct Answer: D - Increased calories Rationale: 1. Infants with CHF have increased metabolic demands due to their heart working harder. 2. Increased caloric intake helps meet the energy needs for the heart and body. 3. Adequate calories promote growth and development in infants with CHF. Summary of other choices: A. Decreased fat: Fat provides essential fatty acids and energy, important for growth and development. Decreasing fat may lead to inadequate energy intake. B. Increased fluids: While fluid restriction may be necessary in some cases of CHF, it is not a primary need. Fluid management is crucial but not the main focus in this scenario. C. Decreased protein: Protein is essential for growth, repair, and immune function. Decreasing protein may lead to muscle wasting and compromised immune function.

Correct Answer: A

Rationale: The correct answer is A: Osteoporosis. Immobility leads to decreased weight-bearing stress on bones, causing bone demineralization and increased risk of osteoporosis. Osteoporosis is characterized by decreased bone density and increased fracture risk. Pooling of blood (B) is more related to circulatory issues. Urinary retention (C) is a result of bladder dysfunction. Susceptibility to infection (D) is not directly related to bone demineralization from immobility.

Correct Answer: B

Rationale: Correct Answer: B (erythroid progenitor: megakaryocyte) Rationale: Erythroid progenitors differentiate into red blood cells, not megakaryocytes. Megakaryocytes arise from megakaryocyte-erythroid progenitors. The mismatch lies in the differentiation pathway. Summary: A: Monocyte progenitor differentiates into macrophages. C: Myeloid progenitor gives rise to neutrophils. D: Lymphoid progenitor differentiates into natural killer cells.

Correct Answer: A

Rationale: The correct answer is A: Gloves only. Monitoring gloves is not relevant when a patient is taking NSAIDs. - B: CNS adverse effects should be monitored due to potential risks such as headaches or dizziness. - C: Cardiac adverse effects should be monitored as NSAIDs can increase the risk of heart attacks or stroke. - D: Renal adverse effects should be monitored because NSAIDs can lead to kidney damage. In summary, monitoring gloves is not necessary when a patient is taking NSAIDs, whereas monitoring CNS, cardiac, and renal adverse effects is essential for patient safety.

Correct Answer: A

Rationale: The correct answer is A because pernicious anemia is caused by a deficiency in vitamin B12, which can occur after gastric bypass surgery due to malabsorption. Excessive fatigue is a common symptom of pernicious anemia. B: Hematuria is associated with kidney or bladder issues, not pernicious anemia. C: Pancytopenia is a decrease in all three blood cell types, not specific to pernicious anemia. D: Epistaxis is nosebleeds, which are not typically associated with pernicious anemia.
