A nurse is caring for a client who has hypertension and has been taking hydrochlorothiazide. Which of the following laboratory values should the nurse evaluate?
Serum electrolyte levels
Thyroid levels
Coagulation studies
Complete blood count
The Correct Answer is A
A. Hydrochlorothiazide can cause electrolyte imbalances, particularly hypokalemia (low potassium levels), hyponatremia (low sodium levels), and hypomagnesemia (low magnesium levels). Monitoring serum electrolyte levels, including potassium, sodium, and magnesium, is essential to detect and manage any abnormalities that may occur as a result of hydrochlorothiazide therapy.
B. Thyroid levels are not typically affected by hydrochlorothiazide therapy. Therefore, monitoring thyroid levels is not necessary in clients taking hydrochlorothiazide for hypertension.
C. Hydrochlorothiazide is not known to affect coagulation studies such as prothrombin time (PT), activated partial thromboplastin time (aPTT), or international normalized ratio (INR).
D. Hydrochlorothiazide is not typically associated with significant hematologic effects that would necessitate routine monitoring of the complete blood count. Therefore, monitoring CBC is not routinely indicated for clients taking hydrochlorothiazide for hypertension.

Correct Answer is D
Explanation
D. Chills are a hallmark sign of febrile nonhemolytic reactions. These reactions typically present with fever, chills, and occasionally rigors (shivering). They are caused by recipient antibodies reacting to donor leukocytes or cytokines present in the transfused blood components.
A. Dyspnea (difficulty breathing) is not typically associated with febrile nonhemolytic reactions. It is more commonly seen in acute hemolytic reactions or transfusion-related acute lung injury (TRALI).
B. Urticaria (hives) is more commonly associated with allergic transfusion reactions rather than febrile nonhemolytic reactions.
C. Vomiting is not a characteristic feature of febrile nonhemolytic reactions. It may occur in some cases of transfusion reactions, but it is not specific to febrile nonhemolytic reactions.
Correct Answer is B
Explanation
B. Headache, particularly a pounding headache or throbbing sensation, is a well-known side effect of nitroglycerin use. It occurs due to the vasodilatory effects of nitroglycerin, which can lead to dilation of blood vessels in the head and neck.
A. Ringing in the ears, also known as tinnitus, is not a common adverse effect of nitroglycerin. Tinnitus is typically associated with certain medications, exposure to loud noises, or underlying medical conditions such as inner ear disorders. It is not a recognized adverse effect of nitroglycerin.
C. Nitroglycerin is not known to increase blood pressure. In fact, it typically causes vasodilation and can lead to a decrease in blood pressure, especially when used sublingually or transdermally. Hypotension, rather than hypertension, is a potential adverse effect of nitroglycerin therapy.
D. Polyuria, or excessive urination, is not a recognized adverse effect of nitroglycerin. Polyuria may occur as a result of other medications or underlying medical conditions affecting renal function, but it is not directly associated with nitroglycerin use.
