Bacterial meningitis alters intracranial physiology, causing:
- A. Cerebral edema
- B. Raised intracranial pressure
- C. Increased permeability of the blood-barrier
- D. All of the above changes
Correct Answer: D
Rationale: Bacterial meningitis can lead to cerebral edema by causing an inflammatory response within the brain tissue. This inflammation can result in the buildup of fluid, leading to edema. Additionally, the inflammatory response can cause an increase in permeability of the blood-brain barrier, allowing substances that are not normally able to cross the barrier to do so. This can lead to further disruption in the balance of fluid within the brain. Finally, the inflammatory response and the buildup of fluid can also result in raised intracranial pressure, which can further exacerbate the physiological changes occurring in the brain. Therefore, all of the above changes - cerebral edema, increased permeability of the blood-brain barrier, and raised intracranial pressure - can be seen in cases of bacterial meningitis.

The nurse, in assessing the adequacy of a client's fluid replacement during the first 2 to 3 days following full- thickness burns to the trunk and right thigh, would be aware that the most significant data would be obtained from recording
- A. Weights every day .
- B. Blood pressure every 15 minutes
- C. Urinary output every hour
- D. Extent of peripheral edema every 4 hours
Correct Answer: C
Rationale: Monitoring urinary output every hour is crucial in assessing the adequacy of fluid replacement in a client with full-thickness burns. Burn injuries can result in a significant loss of fluid and electrolytes due to increased capillary permeability and excessive fluid shift from the intravascular space to the interstitial space. Adequate fluid replacement is essential to maintain tissue perfusion, prevent hypovolemia, and support organ function. By closely monitoring the urinary output every hour, the nurse can assess renal perfusion, fluid balance, and the effectiveness of fluid resuscitation. A decrease in urinary output can indicate inadequate fluid replacement, while an increase may suggest fluid overload. This information is important in guiding adjustments to the fluid replacement therapy to ensure optimal outcomes for the client. Weights, blood pressure measurements, and assessment of peripheral edema are also important data to monitor in a burn client, but urinary output is the most significant indicator of fluid balance in
The major pharmacologic action of albuterol sulfate (Proventil HFA) is:
- A. decreasing airway reactivity.
- B. decreasing inflammation and airway obstruction.
- C. improving the action of cilia to sweep trapped mucous upward.
- D. relaxing constricted bronchial smooth muscle.
Correct Answer: D
Rationale: Albuterol acts as a beta-2 agonist, relaxing bronchial smooth muscle to relieve airway constriction.
A 12-year-old male adolescent, recently diagnosed with Hodgkin lymphoma, shows left cervical and supraclavicular lymph node involvement and drenching night sweats. Based on Ann Arbor Classification, the patient is classified as
- A. stage IA
- B. stage IB
- C. stage IIA
- D. stage IIB
Correct Answer: D
Rationale: Involvement of two lymph node regions above the diaphragm with systemic symptoms corresponds to stage IIB.
The newborn with severe jaundice is at risk for developing:
- A. encephalopathy.
- B. bullous impetigo.
- C. respiratory distress.
- D. blood incompatibility.
Correct Answer: A
Rationale: Severe jaundice in a newborn puts them at risk for developing encephalopathy, which is a condition where bilirubin levels are significantly elevated and can lead to central nervous system dysfunction. If untreated or not managed promptly, high levels of bilirubin can potentially lead to brain damage. It is crucial to monitor and treat severe jaundice in newborns to prevent neurological complications like encephalopathy. Options B, C, and D are not directly associated with severe jaundice in newborns.
A client with suspected lung cancer is scheduled for thoracentesis as part of the diagnostic workup. The nurse reviews the client's history for conditions that might contraindicate this procedure. Which condition is a contraindication for thoracentesis?
- A. A seizure disorder
- B. Anemia
- C. Chronic obstructive pulmonary disease
- D. A bleeding disorder
Correct Answer: D
Rationale: A bleeding disorder is a contraindication for thoracentesis because the procedure involves inserting a needle through the chest wall into the pleural space to drain fluid. Individuals with a bleeding disorder are at an increased risk of bleeding complications during and after the procedure. It is important to ensure adequate clotting function before performing a thoracentesis to prevent excessive bleeding. If a client has a bleeding disorder, alternative diagnostic methods may need to be considered to minimize the risks associated with the procedure.
