Correct Answer: D

Rationale: The correct answer is to use a dedicated blood pressure cuff that stays in the room and is used for that patient only. Patients on contact precautions require dedicated equipment to prevent the spread of disease. Using one blood pressure cuff exclusively for the patient on contact precautions helps minimize the risk of transmitting infections to other patients. Choices A, B, and C are incorrect because while wearing protective gear and isolating the patient in a room with negative airflow are important infection control measures, using dedicated equipment for the patient on contact precautions is specifically recommended to prevent the spread of disease in this scenario.

Correct Answer: C

Rationale: After placing the patient back in bed, the nurse should notify the health care provider. This is important because the health care provider needs to be informed of the incident and assess the patient further to ensure no underlying injuries or issues exist. Re-assessing the patient is crucial but notifying the health care provider takes precedence in this situation. Completing an incident report is important for documentation purposes but not the immediate next step. Doing nothing is incorrect as there was an incident involving a fall that needs further evaluation.

Correct Answer: C

Rationale: Measuring the calf circumference of both legs is crucial when assessing for DVT in an immobile patient. A significant increase in the circumference of one calf compared to the other suggests the presence of a deep vein thrombosis. Option A is incorrect because rubbing the lower leg may dislodge a clot if present. Option B is incorrect as elastic stockings should not be removed frequently as this can increase the risk of clot formation. Option D is incorrect as dorsiflexing the foot can lead to pain and should not be done to assess for DVT.

Correct Answer: B

Rationale: When a patient expresses concerns about medication side effects, it is crucial for the healthcare provider to discuss the benefits and risks of the medication with the patient. This approach helps the patient make an informed decision about their treatment. Choice A is incorrect because dismissing the patient's concerns by reassuring them that side effects are rare may not address the patient's specific worries. Choice C, while pharmacists can provide valuable information, the primary responsibility lies with the healthcare provider. Choice D is incorrect as referring the patient to another healthcare provider may disrupt continuity of care and not address the patient's concerns effectively.

Correct Answer: B

Rationale: Tachycardia and low blood pressure are indicative of worsening dehydration in a patient. Tachycardia is the body's compensatory mechanism to maintain cardiac output in response to decreased intravascular volume, while low blood pressure reflects inadequate perfusion due to decreased fluid levels. Bradycardia and shallow respirations are not typical findings in worsening dehydration, and clear lung sounds do not directly correlate with the severity of dehydration.
