A client presents with a temperature of 38°C (100.4°F) and a stiff neck. Which condition should the nurse suspect?

Choice A rationale
A respiratory rate of 28 breaths per minute indicates tachypnea, which is a sign of respiratory distress. Immediate intervention is needed to address the underlying cause and prevent further deterioration of the patient’s condition.
Choice B rationale
A temperature of 38°C (100.4°F) indicates a fever, which may suggest an infection. While this requires medical attention, it is not as immediately critical as respiratory distress.
Choice C rationale
A blood pressure of 140/90 mmHg is considered high, but it does not indicate an immediate need for intervention in the context of COPD. Hypertension should be managed, but it is not an acute emergency.
Choice D rationale
A heart rate of 90 beats per minute is within the normal range and does not indicate an immediate need for intervention. Monitoring the patient’s heart rate is important, but it is not an urgent concern in this scenario.

Choice A rationale
Elevated serum levels of troponin indicate cardiac cellular injury or death. Troponin is a protein released into the bloodstream when heart muscle cells are damaged, such as during a myocardial infarction.
Choice B rationale
Sustained glycogenolysis does not cause elevated troponin levels. Glycogenolysis is the breakdown of glycogen to glucose, primarily occurring in the liver and muscles, not related to troponin release.
Choice C rationale
Acute tubular necrosis does not elevate troponin levels. This condition affects the renal tubules and is typically indicated by elevated creatinine and BUN levels.
Choice D rationale
Troponin is not an acute phase reactant. Acute phase reactants are proteins whose levels change in response to inflammation, such as C-reactive protein (CRP), not troponin.
