Correct Answer: A

Rationale: Administering oxygen is the most appropriate action when a patient is experiencing confusion after surgery because it helps alleviate hypoxia, which may be causing the patient's confusion. Repositioning the patient would not directly address the potential hypoxia issue. Administering IV fluids may be necessary for hydration or other reasons but is not the initial priority in addressing confusion post-surgery. Performing a neurological exam may be important later on to assess the patient's neurological status but should not be the first action taken when confusion is present.

Correct Answer: D

Rationale: The correct answer is D. Dark, tarry stools indicate gastrointestinal bleeding, which is a serious side effect of enoxaparin that requires immediate medical attention. Reporting this finding promptly is crucial to prevent further complications. Choices A, B, and C are within normal ranges and are not directly related to the adverse effects of enoxaparin, so they do not take precedence over the urgent concern of gastrointestinal bleeding.

Correct Answer: B

Rationale: The correct answer is B: 'Increase your intake of whole grains.' Whole grains are beneficial for individuals with hypertension as they can help promote heart health. Whole grains are high in fiber, which can help lower blood pressure. Option A is incorrect as fluid intake should be adequate but not restricted to 2 liters per day. Option C is incorrect as it is recommended to have smaller, more frequent meals rather than 3 large meals to help manage hypertension. Option D is incorrect; although foods high in potassium can be beneficial for hypertension, the most appropriate dietary modification to include in this scenario is increasing whole grain intake.

Correct Answer: B

Rationale: The correct answer is B: 'Place the client in airborne isolation.' Tuberculosis is an airborne disease transmitted through droplet nuclei. Placing the client in airborne isolation helps prevent the spread of the disease to others. Choice A, placing the client in droplet isolation, is incorrect because tuberculosis is not transmitted through large droplets. Choice C, wearing a surgical mask when providing care to the client, is not sufficient as airborne precautions are necessary. Choice D, keeping the client's door closed at all times, does not directly address the prevention of disease transmission in this case.

Correct Answer: C

Rationale: The correct answer is C because the client stating they should only take the inhaler when feeling short of breath indicates a need for further teaching. Clients with asthma should use their inhaler as prescribed, not just when short of breath. Choices A, B, and D demonstrate good asthma management practices. Choice A indicates understanding of using the albuterol inhaler before exercise to prevent exercise-induced symptoms. Choice B mentions the importance of not overusing the inhaler, which can indicate poor asthma control. Choice D shows awareness of rinsing the mouth after using a corticosteroid inhaler to prevent oral thrush.
