Nursing Elites

1. Which factors will the nurse consider when calculating the CURB-65 score for a patient with pneumonia? (Select one that does not apply)

• A. Age
• B. Blood pressure
• C. Respiratory rate
• D. Oxygen saturation

Correct answer: D

Rationale: The correct answer is 'Oxygen saturation.' When calculating the CURB-65 score for a patient with pneumonia, the factors considered include mental status (confusion), BUN (elevated), blood pressure (decreased), respiratory rate (increased), and age (65 and older). Oxygen saturation is not used in the CURB-65 scoring system. While blood pressure, respiratory rate, and age are factors that are used in the calculation of the CURB-65 score, oxygen saturation is not part of the scoring criteria. Therefore, oxygen saturation is the factor that does not apply when calculating the CURB-65 score.

2. For a 6-year-old child hospitalized with moderate edema and mild hypertension associated with acute glomerulonephritis (AGN), which one of the following nursing interventions would be appropriate?

• A. Institute seizure precautions
• B. Weigh the child twice per shift
• C. Encourage the child to eat protein-rich foods
• D. Relieve boredom through physical activity

Correct answer: A

Rationale: Institute seizure precautions. The severity of the acute phase of AGN is variable and unpredictable; therefore, a child with edema, hypertension, and gross hematuria may be subject to complications, and anticipatory preparation such as seizure precautions is needed. Weighing the child twice per shift may be necessary for monitoring fluid balance but is not specifically related to the complications of AGN. Encouraging the child to eat protein-rich foods is important for overall nutrition but does not directly address the potential complications of AGN. Relieving boredom through physical activity is beneficial for overall well-being but is not the priority in this situation where seizure precautions are essential.

3. A child is seen in the emergency department for scarlet fever. Which of the following descriptions of scarlet fever is not correct?

• A. Scarlet fever is caused by infection with group A Streptococcus bacteria.
• B. "Strawberry tongue"? is a characteristic sign.
• C. Petechiae occur on the soft palate.
• D. The pharynx is red and swollen.

Correct answer: C

Rationale: Petechiae on the soft palate are not a typical finding in scarlet fever. Scarlet fever is caused by group A Streptococcus bacteria, often presenting with a strawberry tongue, red and swollen pharynx, and a sandpaper-like rash. The presence of petechiae on the soft palate is more commonly associated with conditions like rubella rather than scarlet fever. Therefore, this description is not correct in the context of scarlet fever.

4. 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.

5. A healthcare professional is putting together a presentation on meningitis. Which of the following microorganisms has not been linked to meningitis in humans?

• A. S. pneumoniae
• B. H. influenzae
• C. N. meningitidis
• D. Cl. difficile

Correct answer: D

Rationale: The correct answer is Cl. difficile. Clostridium difficile (C. diff) is not typically associated with meningitis in humans. This bacterium is known to cause severe diarrhea, usually as a result of antibiotic treatment. S. pneumoniae, H. influenzae, and N. meningitidis are all known to be causative agents of meningitis in humans. S. pneumoniae is a common cause of bacterial meningitis, especially in adults. H. influenzae, particularly type b (Hib), used to be a leading cause of meningitis in children before the introduction of the Hib vaccine. N. meningitidis is another significant pathogen responsible for causing meningitis, especially in young adults and adolescents.
