Nursing Elites

1. When caring for premature newborns in an intensive care setting, a nurse carefully monitors oxygen concentration. What is the most common complication of this therapy?

• A. Intraventricular hemorrhage
• B. Retinopathy of prematurity
• C. Bronchopulmonary dysplasia
• D. Necrotizing enterocolitis

Correct answer: B

Rationale: Retinopathy of prematurity is the most common complication in premature infants exposed to high concentrations of oxygen. This condition leads to abnormal blood vessel growth in the retina, which can potentially result in blindness if not managed promptly. Intraventricular hemorrhage, though a significant concern in premature infants, is not directly related to oxygen therapy. Bronchopulmonary dysplasia is primarily associated with mechanical ventilation and oxygen exposure over time, not specifically with oxygen concentration monitoring. Necrotizing enterocolitis is more linked to gastrointestinal issues and is not the most common complication of oxygen therapy in premature newborns.

2. The nurse has just admitted a client with severe depression. From which focus should the nurse identify a priority nursing diagnosis?

• A. Nutrition
• B. Elimination
• C. Activity
• D. Safety

Correct answer: D

Rationale: In severe depression, the priority nursing diagnosis is safety. Individuals with severe depression are at risk of self-harm or suicide. Ensuring the client's safety by implementing measures to prevent harm to themselves or others is crucial. While nutrition, elimination, and activity are important aspects of care, ensuring the client's immediate safety takes precedence in this situation.

3. Postoperative orders for a client undergoing a mitral valve replacement include monitoring pulmonary artery pressure together with pulmonary capillary wedge pressure with a pulmonary artery catheter. This action by the nurse will assess

• A. Right ventricular pressure
• B. Left ventricular end-diastolic pressure
• C. Acid-Base balance
• D. Coronary artery stability

Correct answer: B

Rationale: The correct answer is B: Left ventricular end-diastolic pressure. Pulmonary capillary wedge pressure is used to assess left ventricular end-diastolic pressure. This measurement provides valuable information on the filling pressure of the left ventricle. Choices A, C, and D are incorrect because monitoring pulmonary capillary wedge pressure does not directly assess right ventricular pressure, acid-base balance, or coronary artery stability.

4. What is the most common cause of vaginal bleeding immediately after birth?

• A. Uterine atony
• B. Genital lacerations
• C. Abnormal clotting mechanism
• D. Endometritis

Correct answer: A

Rationale: Vaginal bleeding immediately after birth is most often due to uterine atony, which is the failure of the uterus to contract following delivery. This results in inadequate compression of blood vessels at the placental site, leading to hemorrhage. Genital lacerations and abnormal clotting mechanisms can also cause bleeding but are less common immediately after birth compared to uterine atony. Endometritis, inflammation of the lining of the uterus, usually presents with symptoms like fever and pelvic pain rather than immediate postpartum bleeding.

5. In the provision of preventive care to workers, the nurse must be aware of biological hazards that are harmful to workers and their families, such as:

• A. bacteria, fungi, and insects
• B. noise
• C. toxic metals, poisonous gas fumes, and dust
• D. stress

Correct answer: A

Rationale: The correct answer is A: bacteria, fungi, and insects. Biological hazards in the workplace can include microorganisms like bacteria and fungi that can cause infections, as well as insects that may carry diseases. Noise (choice B) is considered a physical hazard, not a biological one. Toxic metals, poisonous gas fumes, and dust (choice C) are examples of chemical hazards, not biological hazards. While stress (choice D) can be a health concern in the workplace, it is not classified as a biological hazard.
