Correct Answer: C

Rationale: Activated PTT is the correct lab value to monitor for clients on heparin therapy. Activated PTT (partial thromboplastin time) helps assess the effectiveness of heparin therapy by measuring the time it takes for blood to clot. Monitoring activated PTT ensures that the client is within the therapeutic range of heparin to prevent both clotting and bleeding complications. Bleeding time (Choice A) and platelet count (Choice B) are not specific indicators of heparin therapy effectiveness. Clotting time (Choice D) is not as sensitive as activated PTT in monitoring heparin therapy.

Correct Answer: A

Rationale: The correct answer is A: S3 ventricular gallop. An S3 sound is a common finding in congestive heart failure due to fluid overload in the heart. It is associated with decreased ventricular compliance. Choices B, C, and D are incorrect. An apical click is not typically associated with congestive heart failure. A systolic murmur may be heard in conditions like mitral regurgitation but is not specific to congestive heart failure. A split S2 is associated with conditions like pulmonary hypertension, not congestive heart failure.

Correct Answer: C

Rationale: Performing frequent oral care with a tooth sponge is the most appropriate nursing measure in this situation. It helps maintain oral hygiene, prevent dryness, and provide comfort for a client with an NG tube. Allowing the client to melt ice chips may not be suitable immediately post-surgery due to potential risks. Providing mints or swabbing the mouth with glycerin swabs may not address the need for proper oral care and hygiene, which is essential for a client with an NG tube.

Correct Answer: C

Rationale: When evaluating the therapeutic effectiveness of digoxin in a client with heart failure, the nurse should expect to find improved respiratory status and increased urinary output. Digoxin helps improve cardiac output and reduces fluid accumulation, leading to improved breathing and increased urinary output. Choices A, B, and D are incorrect because diaphoresis with decreased urinary output, increased heart rate with increased respirations, and decreased chest pain with decreased blood pressure are not indicative of the therapeutic effectiveness of digoxin in heart failure management.

Correct Answer: D

Rationale: The correct answer is D because fibroids that are asymptomatic usually do not require treatment or removal. The statement 'Fibroids that cause no problems still need to be taken out' indicates a need for further education. Choice A correctly states the frequency of fibroids in women and their age group. Choice B accurately describes fibroids as noncancerous slow-growing tumors. Choice C lists common symptoms associated with uterine fibroids.
