Correct Answer: B

Rationale: In the case of a client with a history of recurrent pulmonary embolism or contraindications to heparin, vena caval interruption may be necessary. Vena caval interruption involves placing a filter device in the inferior vena cava to prevent clots from traveling to the pulmonary circulation. Pulmonary embolectomy is a surgical procedure to remove a clot from the pulmonary artery, which is usually considered in severe or life-threatening cases. Increasing coumadin therapy to achieve a higher INR may be an option but vena caval interruption would be more appropriate in this scenario. Thrombolytic therapy is used in acute cases of pulmonary embolism to dissolve the clot rapidly, but in a recurrent case with contraindications to anticoagulants, vena caval interruption would be a preferred intervention.

Correct Answer: A

Rationale: The 'B' in the SBAR acronym stands for Background. SBAR is a standardized communication tool used in healthcare to effectively communicate critical information. In this context, 'Background' refers to providing relevant information about the patient's history, current status, and any other pertinent details. This information helps ensure clear and concise communication between healthcare providers, enhancing patient care. Choice B, 'Basic,' is incorrect as the 'B' specifically emphasizes the detailed background information. Choices C and D, 'Beginning' and 'Break,' are not accurate in the context of the SBAR communication tool.

Correct Answer: B

Rationale: When a client voluntarily participates in a research study and later decides to withdraw, they have the right to be released from the study without any liability. It is unethical to force a participant to continue in a study against their will as this violates their autonomy and personal rights. Choice A is incorrect as it suggests that the client must reimburse the researchers for charges incurred, which is not typically the case unless agreed upon beforehand. Choice C is incorrect as there is no standard practice prohibiting a participant from future studies just because they withdrew from a current one. Choice D is incorrect because participants always have the right to withdraw from a research study at any time.

Correct Answer: A

Rationale: When deciding on transferring patients between units in a hospital, it is essential to consider the appropriateness of the patient for the receiving unit. The Women's Health Center typically caters to female patients with gynecological or obstetric conditions that do not require intensive monitoring or specialized care. In this scenario, the most suitable patient for transfer to the Women's Health Center would be the 26-year-old woman who had a bowel resection, as her condition aligns more closely with the services provided in that unit. The other options, including a male patient, a critically ill patient on a ventilator, and an elderly patient with Alzheimer's disease, would not be appropriate for transfer to a Women's Health Center due to the specialized care they require, which may not align with the unit's focus and staffing capabilities.

Correct Answer: C

Rationale: Certain tasks can be safely delegated to unlicensed assistive personnel to assist nurses in their workload. Tasks that involve routine activities like incentive spirometry can be delegated. Unlicensed assistive personnel can assist clients with incentive spirometry, helping in promoting lung expansion and preventing respiratory complications. Cleansing a wound with peroxide (Choice A) and irrigating a colostomy (Choice B) involve more complex procedures that should be performed by licensed healthcare providers due to the risk of infection and potential complications. Removing a saline-lock IV (Choice D) requires specialized training and should only be performed by licensed personnel to prevent complications and ensure patient safety. The nurse remains responsible for delegating tasks appropriately and overseeing the care provided by unlicensed assistive personnel.
