Correct Answer: A

Rationale: The correct answer is A: Weight. Monitoring daily weight is crucial in assessing fluid retention and worsening heart failure symptoms. Weight gain can indicate fluid overload, a common complication in heart failure. The other choices (B: Appetite, C: Calorie count, and D: Abdominal girth) are not as directly related to monitoring heart failure severity. Appetite and calorie count may be affected by various factors unrelated to heart failure, while abdominal girth may not provide specific information on fluid status. Monitoring weight allows for early intervention and adjustments in treatment to prevent exacerbation of heart failure symptoms.

Correct Answer: A

Rationale: The correct size of suction catheter for James would be Fr. 5. The selection of suction catheter size is based on the patient's height and weight, as well as the secretions to be cleared. A Fr. 5 catheter is appropriate for an average adult like James, as it balances between being too small or too large. Fr. 12 and Fr. 18 are too large for his size and could cause trauma, while Fr. 10 is slightly larger than needed, increasing the risk of mucosal damage. Therefore, Fr. 5 is the most suitable choice for James.

Correct Answer: D

Rationale: The correct answer is D because sickle cell disease is an autosomal recessive genetic disorder. The disease is caused by inheriting two copies of the abnormal hemoglobin gene (HbS). In choice D, the father is HbA (normal) and the mother is HbS (carrier). This combination ensures that the child will inherit one normal gene and one abnormal gene, making them a carrier like the mother but not affected by the disease. Choices A, B, and C all involve at least one parent who carries the HbS gene, increasing the risk of the child having sickle cell disease.

Correct Answer: A

Rationale: The correct answer is A: Prevent clot formation. Heparin is an anticoagulant that inhibits the formation of blood clots. In DIC (Disseminated Intravascular Coagulation), there is excessive clotting throughout the body, leading to organ damage. By administering heparin, we aim to prevent further clot formation and reduce the risk of complications. Choice B is incorrect because heparin does not increase clot formation; it works to inhibit clotting. Choice C is incorrect as heparin does not directly increase blood flow to target organs. Choice D is also incorrect as heparin does not decrease blood flow to target organs; its primary role is anticoagulation.

Correct Answer: C

Rationale: Objective data are measurable and observable, such as vital signs. Respirations of 16 are a specific numerical measurement that can be quantified. This makes choice C the correct answer as it is factual and quantifiable. Choices A, B, and D are subjective data, as they rely on the patient's feelings or experiences, which are open to interpretation and not measurable. Therefore, the nurse should report choice C as objective data as it provides concrete information for assessment and decision-making.
