A pregnant client with hypertension and cardiac dysrhythmias is admitted to the hospital. Which of the following imbalances should the nurse check for?
- A. Metabolic acidosis
- B. Hypernatremia
- C. Hypomagnesemia
- D. Hypercalcemia
Correct Answer: C
Rationale: Hypomagnesemia (low magnesium levels) should be checked for in a pregnant client with hypertension and cardiac dysrhythmias because magnesium plays a critical role in maintaining normal cardiac function and blood pressure regulation. It can worsen both hypertension and dysrhythmias if deficient. Hypomagnesemia can lead to cardiac arrhythmias, particularly in the setting of existing cardiovascular conditions. Monitoring and addressing magnesium levels is important in managing these conditions and ensuring maternal and fetal well-being during pregnancy. Checking for hypomagnesemia allows for timely intervention and correction to help prevent any complications.

A patient is scheduled for an MRI and asks what to expect. Which of the following responses by the nurse is best?
- A. "It is the measurement of muscle contraction after stimulation by tiny needle electrodes."
- B. "Electrodes will be placed on your scalp to measure activity of the brain."
- C. "A scan of the brain will be done after injection of radioisotope."
- D. "It is a noninvasive test that uses magnetic energy to visualize internal parts."
Correct Answer: D
Rationale: The best response by the nurse in this scenario is option D: "It is a noninvasive test that uses magnetic energy to visualize internal parts." This response provides a clear and accurate description of what an MRI (Magnetic Resonance Imaging) involves. An MRI is a diagnostic test that uses a powerful magnetic field, radio waves, and a computer to create detailed images of the internal structures of the body. It is noninvasive, meaning there are no needles, electrodes, or injections involved. By explaining the procedure in a simple and understandable way, the nurse can help alleviate any anxiety or concerns the patient may have about the upcoming MRI.
How does nosocomial pneumonia occur?
- A. In a healthcare setting
- B. Within 48hrs of admission to a healthcare
- C. In the immunocompromised host facility
- D. In a community setting
Correct Answer: A
Rationale: Nosocomial pneumonia occurs in a healthcare setting. It is a type of pneumonia that is contracted during a hospital stay or other healthcare facilities. The risk of developing nosocomial pneumonia is higher in patients who are already hospitalized due to various medical conditions, surgeries, or use of medical devices like ventilators. The infection can be caused by different types of bacteria, viruses, or fungi present in the healthcare environment. Preventive measures, such as proper hand hygiene, infection control practices, and minimizing the use of invasive devices, are crucial in reducing the incidence of nosocomial pneumonia.
Alice is rushed to the emergency department during an acute, severe prolonged asthma attack and is unresponsive to usual treatment. The condition is referred to as which of the following?
- A. Status asthmaticus
- B. Reactive airway disease
- C. Intrinsic asthma
- D. Extrinsic asthma 49
Correct Answer: A
Rationale: Status asthmaticus is a severe and persistent asthma attack that does not respond to standard treatments like inhalers or nebulizers. It is a life-threatening condition that can lead to respiratory failure if not treated promptly. Patients with status asthmaticus may require IV medications, oxygen therapy, and possibly mechanical ventilation to support their breathing. It is a medical emergency that requires immediate intervention to prevent serious complications and potential death.
Recent studies indicate that a deficiency of which vitamin correlates with increased morbidity and mortality in children with measles?
- A. A
- B. C
- C. Niacin
- D. Folic acid
Correct Answer: A
Rationale: Recent studies have shown that a deficiency of vitamin A correlates with increased morbidity and mortality in children with measles. Vitamin A plays a crucial role in supporting the immune system and helps protect against severe complications of measles, such as pneumonia and vision problems. Children with measles are at higher risk of vitamin A deficiency due to factors such as decreased intake and increased utilization of vitamin A during infection. Providing vitamin A supplementation to children with measles has been shown to reduce the severity of the disease and improve outcomes. Therefore, ensuring adequate vitamin A levels is essential in the management of children with measles to reduce morbidity and mortality.
