Fundamentals Nursing Process Questions

Correct Answer: C

Rationale: The correct answer is C because administering antiemetic medications like metoclopramide and dexamethasone helps control nausea and vomiting post-chemotherapy. Metoclopramide acts on the gut to reduce nausea, while dexamethasone decreases inflammation and suppresses the vomiting reflex. Choice A focuses on dietary interventions but does not address the physiological cause of nausea. Choice B with breathing exercises may help some clients but does not directly address the nausea and vomiting. Choice D is incorrect as withholding fluids can lead to dehydration, which is not recommended after chemotherapy.

Correct Answer: C

Rationale: The correct answer is C: 0.90% sodium chloride. When administering a hypotonic solution like 0.45% sodium chloride or 5% dextrose in water, water moves into the cells causing them to swell. This can exacerbate symptoms of hypovolemia such as low blood pressure and decreased perfusion. However, 0.90% sodium chloride is an isotonic solution and will not further exacerbate hypovolemic symptoms. Choices A, B, and D are hypotonic solutions that can worsen hypovolemic symptoms by causing cellular swelling.

Correct Answer: B

Rationale: The correct answer is B: Pallor. Pallor, which refers to paleness of the skin, is an early sign of anemia due to decreased red blood cell levels. Anemia causes reduced oxygen delivery to tissues, leading to paleness. Palpitations (A) may occur in anemia but are not an early sign. Glossitis (C) and weight loss (D) are not typically early signs of anemia and are more commonly associated with other health conditions.

Correct Answer: C

Rationale: The correct answer is C: Fat. Excessive ingestion of fat has been linked to autoimmunity due to its potential to trigger inflammation in the body, which can disrupt the immune system's balance and lead to autoimmune responses. High-fat diets have been associated with increased production of pro-inflammatory molecules, impacting immune function negatively. Protein (choice A) is essential for immune function, vitamin A (choice B) supports immune responses, and zinc (choice D) is crucial for immune system regulation. However, excessive intake of these nutrients typically does not directly lead to autoimmunity like excessive fat consumption does.

Correct Answer: D

Rationale: The correct answer is D: vasopressin (Pitressin). In diabetes insipidus, there is a deficiency of antidiuretic hormone (ADH), which leads to excessive urination and thirst. Vasopressin is a synthetic form of ADH that helps regulate water balance by reducing urine output. Therefore, administering vasopressin would help manage the symptoms of diabetes insipidus. Insulin (A) is used for diabetes mellitus, not diabetes insipidus. Potassium chloride (B) is used to correct potassium imbalances, not specific to diabetes insipidus. Furosemide (Lasix) (C) is a diuretic that increases urine output, which would worsen the symptoms of diabetes insipidus.
