A nurse is providing teaching to a client who has chronic rheumatoid arthritis and a new prescription for hydroxychloroquine. The nurse should instruct the client to obtain which of the following diagnostic studies routinely?

Eye examination

Chest -ray

Pancreatic enzyme levels

Urinalysis screening

Answer and Explanation

The Correct Answer is A

When providing teaching to a client with chronic rheumatoid arthritis who is starting a new prescription for hydroxychloroquine, the nurse should instruct the client to obtain routine eye examinations. Hydroxychloroquine is an antimalarial and immunosuppressive medication commonly used to treat rheumatoid arthritis and other autoimmune conditions.

One of the potential side effects of hydroxychloroquine is ocular toxicity, particularly affecting the retina. Retinal toxicity can lead to vision changes or, in severe cases, irreversible damage to the eyes. Therefore, regular eye examinations are necessary to monitor for any signs of retinal toxicity and detect any visual changes early to prevent further complications.

The American Academy of Ophthalmology recommends that patients taking hydroxychloroquine undergo a baseline eye examination before starting the medication and annual eye examinations thereafter, especially after five years of continuous use.

Let's go through the other options:

B. Chest x-ray: A chest x-ray is not routinely required for monitoring clients taking hydroxychloroquine for rheumatoid arthritis. Hydroxychloroquine is not known to cause significant respiratory or pulmonary side effects.

C. Pancreatic enzyme levels: Monitoring pancreatic enzyme levels is not specifically related to hydroxychloroquine therapy. Pancreatic enzyme level testing is typically used to assess the function of the pancreas in conditions like pancreatitis or pancreatic insufficiency.

D. Urinalysis screening: While regular monitoring of kidney function is important for clients on long-term medication therapy, routine urinalysis screening is not specifically related to hydroxychloroquine use in clients with rheumatoid arthritis. Regular eye examinations are of higher priority due to the potential ocular toxicity associated with this medication.

Correct Answer is B

Explanation

A. History of asthma:Verapamil is a calcium channel blocker and does not affect the airways or cause bronchospasm, unlike beta-blockers, which can exacerbate asthma.

B. History of heart failure:Verapamil has negative inotropic effects, meaning it decreases the strength of heart contractions. This can exacerbate heart failure, particularly in clients with reduced ejection fraction (systolic heart failure). It is generally contraindicated in clients with severe heart failure as it can worsen symptoms.

C. Systolic BP 110 mm Hg:While verapamil can cause a drop in blood pressure due to its vasodilatory effects, a systolic blood pressure of 110 mm Hg is not an absolute contraindication.

D. A blood creatinine level of 1.0 mg/dL is within the normal range (approximately 0.6–1.2 mg/dL for adults). Verapamil is not contraindicated in clients with normal renal function.

A. Hgb 14 g/dL B. WBC count 10,000/mm3 C. INR 2.0 D. Platelets 150,000/mm3

Correct Answer is C

Explanation

A. Hemoglobin level: The hemoglobin level measures the amount of hemoglobin, the oxygen-carrying protein in red blood cells, in the blood. Warfarin is not directly responsible for increasing or decreasing the hemoglobin level. While warfarin can lead to bleeding complications in some cases, it does not specifically target the hemoglobin level, so it is not a direct indicator of the medication's effectiveness.

B. Platelet count: The platelet count measures the number of platelets in the blood, which are essential for blood clotting. Warfarin does not directly affect platelet production or count. It works by inhibiting the production of certain clotting factors, not by affecting platelets. Monitoring the platelet count is important, but it is not an indicator of warfarin's effectiveness in preventing excessive clotting.

C. Prothrombin time (PT) or activated partial thromboplastin time (aPTT): Prothrombin time (PT) and activated partial thromboplastin time (aPTT) are coagulation tests used to assess different types of anticoagulant medications, such as heparin. Warfarin's effect is measured using the International Normalized Ratio (INR). PT and aPTT are not specific to warfarin therapy and are not used to monitor its effectiveness. The INR is the appropriate laboratory test for assessing the efficacy of warfarin therapy.

D. International Normalized Ratio (INR): This is the correct answer. The International Normalized Ratio (INR) is the laboratory test used to monitor the effectiveness of warfarin therapy. The INR measures the time it takes for the blood to clot and reflects the anticoagulant effect of warfarin. A therapeutic INR within the target range (e.g., INR = 2.0 to 3.0 for most indications) indicates that warfarin has been effective in preventing excessive clotting and reducing the risk of complications associated with blood clots.
