A nurse develops a nursing diagnostic statement for a patient with a medical diagnosis of pneumonia with chest x-ray results of lower lobe infiltrates. Which nursing diagnosis did the nurse write?
Risk for infection related to chest x-ray procedure
Impaired gas exchange related to alveolar-capillary membrane changes
Risk for deficient fluid volume related to dehydration
Ineffective breathing pattern related to pneumonia
The Correct Answer is B
A. "Risk for infection related to chest x-ray procedure" is not an appropriate diagnosis because a chest x-ray is a diagnostic tool, and pneumonia itself is the concern for infection.
B. "Impaired gas exchange related to alveolar-capillary membrane changes" is correct as pneumonia causes inflammation and consolidation in the lungs, which directly impacts gas exchange.
C. "Risk for deficient fluid volume related to dehydration" does not apply specifically to pneumonia unless the patient presents signs of dehydration, which is not indicated in the scenario.
D. "Ineffective breathing pattern related to pneumonia" could also be a valid diagnosis, but the primary concern given the information provided is gas exchange impairment.

Correct Answer is C
Explanation
A. Weak quadriceps muscles can occur with electrolyte imbalances, but the provided values do not indicate hypokalemia or other issues causing muscle weakness.
B. Decreased deep tendon reflexes are generally associated with elevated calcium levels or other electrolyte disturbances but are not specifically indicated by the given lab values.
C. A calcium level of 4.5 mg/dL is significantly low (normal range is typically around 8.5-10.5 mg/dL), which can lead to hypocalcemia symptoms such as tingling of the extremities and tetany due to increased neuromuscular excitability.
D. Light-headedness when standing up (orthostatic hypotension) is more related to fluid volume status or dehydration rather than directly related to the given electrolyte levels.
Correct Answer is B
Explanation
A. While the patient may have been in a life-threatening situation, this point is not necessarily a direct indictment of the nurse’s actions but rather a justification for performing CPR.
B. The prosecution will likely focus on whether the CPR was performed according to accepted standards of care. If it can be shown that the technique was inappropriate or negligent, this would support the claim of malpractice.
C. Performing CPR according to policy may serve as a defense for the nurse, emphasizing adherence to established protocols.
D. While it is true that older adults with brittle bones may be at risk for fractures, this is a known risk of CPR, and the prosecution will aim to demonstrate specific negligence or failure in technique rather than just acknowledging inherent risks.
