Correct Answer: D

Rationale: The nurse should see the patient with a hip replacement experiencing chest pain and dyspnea first because these symptoms could indicate a pulmonary embolism, which is a life-threatening condition requiring immediate attention. The other patients also need care, but urgent assessment and intervention are crucial in the case of potential pulmonary embolism to prevent serious complications or death.

Correct Answer: D

Rationale: The correct answer is to call the provider for clarification. When faced with a higher-than-usual dose of medication, the nurse's first action should be to contact the prescribing healthcare provider to confirm the dosage. Administering the medication without clarifying the dose with the provider can pose serious risks to the patient's safety. Holding the medication and consulting the pharmacist may be appropriate after contacting the provider for clarification. Asking another nurse to verify the dose is not the most appropriate action when dealing with an unusual prescription; direct communication with the provider is essential in such situations.

Correct Answer: B

Rationale: Checking the placement of the NG tube before each feeding is crucial as it ensures the tube is correctly positioned, reducing the risk of complications such as aspiration or improper delivery of feedings. Flushing the NG tube with water before and after each feeding can disrupt the feeding schedule and is not a standard procedure. Administering medications through the NG tube every 4 hours may not be necessary for all patients and should be based on specific medication requirements. Increasing the feeding rate without proper assessment and monitoring can lead to feeding intolerance or complications, making it an inappropriate intervention.

Correct Answer: B

Rationale: The most appropriate action when finding incomplete documentation is to notify the nurse manager of the issue. This ensures that accurate records are maintained and the situation can be addressed properly. Completing the missing documentation on behalf of someone else may lead to inaccuracies, asking the nurse to complete it may not guarantee timely correction, and confronting the nurse could create a confrontational situation that is not conducive to effective teamwork.

Correct Answer: B

Rationale: The correct answer is to measure the calf circumference of both legs when assessing a patient for possible DVT. An increase in calf circumference in one leg can indicate the presence of a DVT. Option A is incorrect because dorsiflexing the foot and checking for pain are not primary assessments for DVT. Option C is incorrect as redness of the skin may not always be present in cases of DVT. Option D is incorrect as performing a Doppler ultrasound scan is usually done after clinical assessment and to confirm the diagnosis, not as the initial priority assessment.
