Explanation
A. Severe pain in the abdomen and joints. Severe pain is the hallmark symptom of a sickle cell crisis, often occurring in the abdomen, joints, and bones due to vaso-occlusive events.
B. Fever and chills. While fever can be a sign of infection in individuals with sickle cell disease, it is not the most common symptom during a sickle cell crisis.
C. Cough and shortness of breath. These symptoms are more indicative of respiratory infections or complications like acute chest syndrome but are not the primary symptoms of a sickle cell crisis.
D. Numbness and tingling in the extremities. These symptoms are not typically associated with a sickle cell crisis.
Correct Answer is D
Explanation
A. "Dietary supplements have not been tested and approved by the government." While this statement may be true, it is not directly related to the potential interaction between dietary supplements and nitroglycerin.
B. "Dietary supplements may be expensive and are not typically covered by insurance." While cost considerations are important, they are not directly related to the potential interaction
between dietary supplements and nitroglycerin.
C. "There is not enough evidence that dietary supplements are effective for erectile dysfunction."
While this statement may be true, it is not directly related to the potential interaction between dietary supplements and nitroglycerin.
D. "Dietary supplements can cause a drug-drug interaction with nitrates." Nitroglycerin is a medication commonly used for angina, and it interacts with erectile dysfunction medications
such as sildenafil (Viagra) due to its vasodilatory effects, potentially causing severe hypotension.
Therefore, it is crucial for the nurse to educate the client about the risk of interactions between dietary supplements and nitroglycerin.
