Correct Answer: B

Rationale: The platelet count is the most appropriate laboratory result to review in a client presenting with petechiae and ecchymosis. Petechiae and ecchymosis are indicative of potential bleeding issues, which can be caused by low platelet count or impaired platelet function. Platelets are essential for clotting, and a low platelet count can lead to bleeding disorders. Reviewing the platelet count will provide valuable information about the client's clotting ability. Choice A, red blood cell count, is not typically associated with petechiae and ecchymosis. Hemoglobin levels (Choice C) are more related to anemia than bleeding disorders like thrombocytopenia. White blood cell count (Choice D) is not directly linked to the presence of petechiae and ecchymosis, which are more specific to platelet-related issues.

Correct Answer: A

Rationale: The correct answer is weight loss. In hyperthyroidism, there is an excess production of thyroid hormones leading to an increased metabolic rate. This increased metabolism can result in weight loss despite normal or increased appetite. Choice B (Weight gain) is more commonly associated with hypothyroidism where the metabolic rate is decreased. Choice C (Tachycardia) is another common symptom of hyperthyroidism due to the effects of thyroid hormones on the heart, causing an increased heart rate. Choice D (Dry skin) is not a typical symptom of hyperthyroidism; instead, it is more commonly associated with hypothyroidism.

Correct Answer: A

Rationale: The correct answer is A: Hypertension. Epoetin alfa (Epogen) is a medication used to treat anemia in clients with chronic renal failure. One common side effect of this medication is hypertension. Epoetin alfa stimulates red blood cell production, which can lead to an increase in blood pressure. Therefore, the nurse should closely monitor the client for signs and symptoms of hypertension while on this medication. Choices B, C, and D are incorrect. Hypotension is not typically associated with epoetin alfa administration. Infection is not a direct side effect of epoetin alfa. Edema is also not a common side effect of this medication.

Correct Answer: C

Rationale: Daily weight is the most crucial parameter to assess when evaluating the effects of peritoneal dialysis because it directly reflects fluid balance. Peritoneal dialysis involves the removal of excess fluid and waste products from the body. Monitoring daily weight enables the healthcare provider to track changes in fluid status, ensuring that the dialysis treatment is effective. While serum potassium levels, blood pressure, and serum sodium levels are important parameters to monitor in patients undergoing dialysis, they are not as directly indicative of the immediate effects of peritoneal dialysis on fluid balance as daily weight.

Correct Answer: B

Rationale: The correct answer is B: Decreased lung elasticity. Chronic obstructive pulmonary disease (COPD) is characterized by a loss of lung elasticity, which leads to difficulty in exhaling air. This decreased elasticity results in air becoming trapped in the lungs, making it challenging for the individual to breathe effectively. Choice A is incorrect as COPD is associated with decreased lung compliance, not increased compliance. Choice C is incorrect as individuals with COPD often have a decreased respiratory rate due to impaired lung function. Choice D is incorrect as COPD causes limited lung expansion due to factors like air trapping and hyperinflation.
