To assess the kidney function of a patient with an indwelling urinary (Foley) catheter, the nurse measures the hourly urine output. When should she notify the physician?

Correct Answer: A

Rationale: Notifying the physician is necessary when the urine output is less than 30 ml/hour as it indicates impaired kidney function. Adequate urine output is essential for monitoring kidney function, and a urine output less than 30 ml/hour could suggest potential renal issues that require medical attention.

Correct Answer: B

Rationale: The correct answer is B. An elderly patient who is incontinent, bedridden, and suffering from a serious illness like gastric cancer is at the highest risk for developing pressure ulcers. Being bedridden and incontinent increases the pressure on certain areas of the body, leading to tissue damage and the development of pressure ulcers. Additionally, the patient's age and underlying health condition further contribute to their risk. It is crucial to identify and address such risk factors promptly to prevent the occurrence of pressure ulcers in vulnerable patients.

Correct Answer: D

Rationale: The scenario described involves a breach of duty by the healthcare provider to properly supervise the infant, resulting in harm. This failure to meet the standard of care falls under the category of malpractice, which refers to professional negligence or misconduct. Malpractice specifically applies to situations where a healthcare provider's actions or omissions deviate from the accepted standard of care, causing harm to a patient. In this case, the nurse's lack of supervision leading to the infant falling off the scale and sustaining a skull fracture would be considered malpractice.

Correct Answer: D

Rationale: As individuals age, various changes occur in the vascular system. These changes include increased peripheral resistance of the blood vessels, decreased blood flow, and an increased workload of the left ventricle. Therefore, all the listed changes result from aging, making option D, 'All of the above,' the correct answer.

Correct Answer: B

Rationale: Before administering a blood transfusion, it is crucial to perform blood typing and cross-matching to ensure compatibility between the donor's blood and the recipient's blood. This process helps prevent adverse reactions such as transfusion reactions, which can be life-threatening. Prothrombin and coagulation time, bleeding and clotting time, as well as CBC and electrolyte levels are important tests in other clinical contexts, but for blood transfusions, blood typing and cross-matching are essential to ensure patient safety.

Correct Answer: C

Rationale: The incorrect statement is that 'The patient should always feed himself.' Patients with dysphagia may require assistance with feeding due to difficulty in swallowing safely. It is essential to provide appropriate support and supervision during meal times to prevent complications such as aspiration or inadequate nutrition intake.

Correct Answer: C

Rationale: Primary nursing care units have been proven to be highly satisfying for both patients and nurses. This model promotes a consistent and continuous relationship between a patient and a primary nurse, leading to improved communication, personalized care, and overall satisfaction for both parties involved.

Correct Answer: D

Rationale: Chest physiotherapy is the most effective intervention in cases of impaired gas exchange related to increased secretions. This technique helps mobilize and clear secretions from the airways, thereby improving gas exchange in the lungs. Placing a humidifier or administering oxygen by high humidity face mask may provide moisture but may not directly address the clearance of secretions. Encouraging increased fluid intake can help with hydration but may not address the underlying issue of impaired gas exchange due to secretions.
