A nurse is reviewing the health record of a client who asks about using propranolol to treat hypertension.
The nurse should recognize which of the following conditions is a contraindication for taking propranolol?
Tachycardia.
Asthma.
Hypertension.
Glaucoma.
The Correct Answer is B
Propranolol is a beta-blocker that can cause bronchoconstriction and worsen asthma symptoms.
Asthma is a reversible airway disease that is a contraindication for taking propranolol.
Choice A, tachycardia, is not a contraindication for taking propranolol. In fact, propranolol can be used to treat some types of tachycardia, such as atrial fibrillation or supraventricular tachycardia, by slowing down the heart rate.
Choice C, hypertension, is not a contraindication for taking propranolol. Propranolol can be used to treat hypertension by reducing the cardiac output and peripheral resistance.
Choice D, glaucoma, is not a contraindication for taking propranolol. Propranolol does not affect the intraocular pressure or the aqueous humor production. However, some other beta-blockers, such as timolol, can be used to treat glaucoma by lowering the intraocular pressure.

Correct Answer is B
Explanation
The nurse should contact the provider before administering furosemide because the patient has a low serum potassium level of 2.8 mEq/L, which is below the normal range of 3.5 to 5.0 mEq/L.Furosemide is a diuretic that can cause potassium loss and worsen hypokalemia, which can lead to cardiac arrhythmias, muscle weakness, and fatigue. The nurse should also monitor the patient’s blood pressure, weight, and urine output, as furosemide can lower blood pressure and cause dehydration.
Choice A. Administer medication is wrong because the nurse should not give furosemide without checking with the provider first, as it could be harmful to the patient with low potassium.
Choice C. Hold medication is wrong because the nurse should not withhold furosemide without a valid reason or an order from the provider, as it could cause fluid overload and worsen the patient’s condition.
Choice D. Give potassium supplement is wrong because the nurse should not give potassium supplement without an order from the provider, as it could cause hyperkalemia or interact with other medications.
Correct Answer is D
Explanation
Thiazide diuretics are sulfa-containing drugs and can cause allergic reactions in patients who are sensitive to sulfa compounds.These reactions can include headaches, rash, hives, swelling of the mouth and lips, wheezing or trouble breathing, asthma attack, and anaphylaxis.
Choice A is wrong because iodine is not a component of thiazide diuretics and is not related to sulfa allergy.
Choice B is wrong because latex is not a component of thiazide diuretics and is not related to sulfa allergy.
Choice C is wrong because shellfish is not a component of thiazide diuretics and is not related to sulfa allergy.
Shellfish allergy is usually caused by a protein called tropomyosin, not by iodine or sulfa compounds.
Thiazide diuretics are drugs that inhibit the reabsorption of sodium and water in the distal convoluted tubule of the kidney, leading to increased urine output.They are used to treat hypertension, edema, heart failure, and some kidney diseases.Some examples of thiazide diuretics are hydrochlorothiazide, chlorthalidone, and indapamide.
