Correct Answer: D

Rationale: An irregularly shaped mole is a priority finding to report to the provider as it can be indicative of melanoma, a type of skin cancer. Melanoma is a serious condition that requires prompt evaluation and treatment. Raised nevus, macule, and vesicle are common skin findings that are typically benign and may not require immediate attention. Therefore, the irregularly shaped mole stands out as the priority due to its association with potential malignancy.

Correct Answer: D

Rationale: The correct answer is D, International normalized ratio (INR). INR is used to monitor the therapeutic effect of warfarin, an anticoagulant medication. Warfarin works by inhibiting the synthesis of vitamin K-dependent clotting factors. Monitoring the INR helps assess how well the medication is working to prevent blood clots. Choices A, B, and C are not specific indicators for monitoring the effectiveness of warfarin. Hemoglobin levels primarily assess the oxygen-carrying capacity of red blood cells, platelet count evaluates the clotting ability of blood, and PT measures the time it takes for blood to clot. While these values are important for overall health assessment, they do not directly reflect the anticoagulant effects of warfarin.

Correct Answer: D

Rationale: The correct action for the nurse to take when continuous bubbling is noted in the water seal chamber of a chest tube is to apply a dressing over the insertion site. Continuous bubbling indicates an air leak, and applying a dressing helps manage this issue by providing a seal. Clamping the chest tube or replacing the drainage system is not appropriate in this situation as it can lead to complications such as tension pneumothorax or inadequate drainage of the pleural space.

Correct Answer: B

Rationale: The correct answer is B. An apical pulse below 60/min indicates bradycardia, a potential sign of digoxin toxicity. The nurse should report this finding to the provider for further evaluation and possible adjustment of the digoxin dose. Choice A, a potassium level of 4.2 mEq/L, is within the normal range (3.5-5.0 mEq/L) and does not indicate toxicity. Choice C, a digoxin level of 1 ng/ml, is within the therapeutic range (0.5-2 ng/ml) and is not suggestive of toxicity. Choice D, constipation for 2 days, is not directly related to digoxin administration and would not require an immediate report to the provider.

Correct Answer: B

Rationale: The correct answer is B. Therapeutic groups indeed encourage members to focus on particular issues. This focus helps individuals address specific concerns, work through challenges, and support one another in a structured setting. Choice A is incorrect because therapeutic groups typically promote a democratic structure that values input from all members rather than an autocratic one. Choice C is incorrect as therapeutic groups can be led by various mental health professionals, not solely by licensed psychiatrists. Choice D is incorrect; therapeutic groups aim to foster independent growth and self-reliance rather than promoting dependent relationships.
