Nursing Elites

1. A patient is being admitted to the ICU with a severe case of encephalitis. Which of these drugs would the nurse not expect to be prescribed for this condition?

• A. Acyclovir (Zovirax)
• B. Mannitol (Osmitrol)
• C. Lactated Ringer's
• D. Phenytoin (Dilantin)

Correct answer: C

Rationale: In the treatment of encephalitis, medications like Acyclovir and Phenytoin are commonly prescribed. Acyclovir is an antiviral medication used to treat viral infections like herpes simplex virus, which can cause encephalitis. Phenytoin is an antiepileptic drug that may be used to manage seizures associated with encephalitis. Mannitol is a diuretic used to reduce intracranial pressure (ICP) by decreasing cerebral edema. Lactated Ringer's solution, on the other hand, is primarily used in fluid replacement therapy and may not be indicated if a patient is at risk for high ICP, as excessive fluid administration could worsen cerebral edema and increase ICP.

2. A patient with severe mitral regurgitation and decreased cardiac output is being cared for by a nurse. The nurse assesses the patient for mental status changes. What is the rationale for this intervention?

• A. Decreased cardiac output can cause hypoxia to the brain
• B. Mental status changes may be a side effect of the patient's medication
• C. Mitral regurgitation is a complication associated with some neurological disorders
• D. The patient may be confused about his diagnosis

Correct answer: A

Rationale: When caring for a patient with severe mitral regurgitation and decreased cardiac output, assessing for mental status changes is crucial. Decreased cardiac output can lead to inadequate perfusion and oxygenation of vital organs, including the brain, resulting in hypoxia. This hypoxia can manifest as mental status changes such as confusion, restlessness, or lethargy. Therefore, monitoring mental status helps in identifying potential hypoxic states and guiding appropriate interventions. The other options are incorrect as they do not directly correlate decreased cardiac output with potential hypoxia-induced mental status changes.

3. After an unimmunized individual is exposed to hepatitis B through a needle-stick injury, which actions will the nurse plan to take (select one that does not apply)?

• A. Administer hepatitis B vaccine.
• B. Test for antibodies to hepatitis B.
• C. Teach about alpha-interferon therapy.
• D. Give hepatitis B immune globulin.

Correct answer: C

Rationale: In the case of exposure to hepatitis B, the nurse should plan to administer hepatitis B vaccine to provide active immunity. Testing for antibodies to hepatitis B is essential to determine the individual's immune status. Giving hepatitis B immune globulin is necessary for passive immunity in cases of exposure. However, teaching about alpha-interferon therapy is not part of the standard management for hepatitis B exposure. Interferon therapy and oral antivirals are typically used in the treatment of chronic hepatitis B infections, not for prophylaxis after exposure.

4. The nurse is caring for a client in the late stages of Amyotrophic Lateral Sclerosis (A.L.S.). Which finding would the nurse expect?

• A. Confusion
• B. Loss of half of the visual field
• C. Shallow respirations
• D. Tonic-clonic seizures

Correct answer: C

Rationale: In the late stages of Amyotrophic Lateral Sclerosis (A.L.S.), respiratory muscles are affected, leading to shallow respirations. Confusion is not typically associated with A.L.S. Loss of half of the visual field suggests a neurological issue unrelated to A.L.S., while tonic-clonic seizures are not commonly seen in A.L.S. patients. Shallow respirations are a hallmark sign of respiratory muscle weakness in A.L.S. due to the degeneration of motor neurons.

5. The nurse reviews the record of a child who is suspected to have glomerulonephritis and expects to note which finding that is associated with this diagnosis?

• A. Hypotension
• B. Brown-colored urine
• C. Low urinary specific gravity
• D. Low blood urea nitrogen level

Correct answer: B

Rationale: Glomerulonephritis refers to a group of kidney disorders characterized by inflammatory injury in the glomerulus. Gross hematuria resulting in dark, smoky, cola-colored, or brown-colored urine is a classic symptom of glomerulonephritis. Hypertension is also common. Blood urea nitrogen levels may be elevated. A moderately elevated to high urinary specific gravity is associated with glomerulonephritis.
