Correct Answer: C

Rationale: Objective data are measurable and observable facts. Respirations (C) of 16 per minute is objective data as it is a quantifiable measurement that can be counted and recorded. It is not influenced by personal interpretation or bias. Choices A, B, and D are subjective data as they rely on the patient's feelings, perceptions, or symptoms, which can vary and are open to interpretation. Therefore, choice C is the correct answer as it represents concrete, verifiable information that can be used in the patient's assessment and care planning.

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: D

Rationale: Correct Answer: D - Lubricating eye drops Rationale: Lubricating eye drops help prevent complications such as corneal abrasions in patients with Bell's Palsy by keeping the eye moist and preventing dryness. Bell's Palsy can cause difficulty in closing the eye properly, leading to dryness and potential damage to the cornea. Using lubricating eye drops helps maintain eye health. Summary of Incorrect Choices: A: Megavitamin therapy - Not directly related to preventing complications in Bell's Palsy. B: Application of ice to the affected area - Ice may not address eye dryness or prevent corneal abrasions. C: Elastic bandages - Not relevant to preventing complications associated with Bell's Palsy.

Correct Answer: C

Rationale: The correct answer is C: Cooked vegetables. Cooking vegetables helps to kill harmful bacteria and parasites that may pose a risk of infection to an immunocompromised individual like a patient with HIV. Raw fruits (A) and raw vegetables (B) may carry pathogens that can be dangerous for someone with a weakened immune system. Caesar dressing (D) may contain raw eggs, which also pose a risk for infection. Therefore, choosing cooked vegetables is the safest option to reduce the risk of infection for the patient with HIV.

Correct Answer: B

Rationale: The correct answer is B: Help the client don thromboembolic stocking or support hose during waking hours. This intervention helps decrease the risk for thrombus formation in polycythemia vera by promoting venous return and preventing blood pooling in the lower extremities. Compression stockings improve circulation and reduce the risk of blood clots. Isometric exercises (choice A) may increase blood pressure and heart rate, potentially worsening the risk of thrombus formation. Drinking excess fluid (choice C) can lead to hypervolemia and increase the risk of clotting. Resting immediately if chest pain develops (choice D) is important but does not directly address the prevention of thrombus formation in polycythemia vera.
