A client recently diagnosed with hypertension is prescribed a thiazide diuretic. Which condition below would be a contraindication associated with thiazide diuretics?

Renal failure

Hypertension

Heart failure

Idiopathic hypercalciuria

Answer and Explanation

The Correct Answer is A

Choice A reason:

Renal failure is a contraindication for thiazide diuretics because these medications require adequate kidney function to be effective. In renal failure, the kidneys are not able to filter and excrete the medication properly, which can lead to toxic accumulation and adverse effects.

Choice B reason:

Hypertension is an indication for thiazide diuretics, not a contraindication. These medications are commonly used to help control high blood pressure by reducing fluid volume in the body.

Choice C reason:

Heart failure can be managed with thiazide diuretics as they help reduce fluid overload and improve symptoms. It is not a contraindication for this class of medication.

Choice D reason:

Idiopathic hypercalciuria, a condition of elevated calcium levels in the urine, can actually be managed with thiazide diuretics. These medications help reduce the amount of calcium excreted in the urine, making them beneficial rather than contraindicated.

Correct Answer is C

Explanation

Choice A reason:

Platelets are involved in blood clotting and do not play a role in oxygen transport. Their primary function is to prevent bleeding by forming clots in damaged blood vessels.

Choice B reason:

Neutrophils are a type of white blood cell that helps fight infection. They are part of the immune system and do not transport oxygen.

Choice C reason:

Hemoglobin, a protein found in red blood cells, is responsible for transporting oxygen from the lungs to the tissues and carbon dioxide from the tissues back to the lungs. It binds with oxygen in the lungs and releases it in the body’s tissues, playing a critical role in respiratory gas exchange.

Choice D reason:

Lymphocytes are another type of white blood cell involved in the immune response. They do not carry oxygen but are vital for fighting infections and producing antibodies.

A. Reposition the client every 2 hours. B. Massage the skin over the client's bony prominences. C. Position the client in high Fowler's. D. Apply cornstarch to keep sensitive skin areas dry.

Correct Answer is A

Explanation

Choice A reason:

Repositioning the client every 2 hours is a standard preventive measure to reduce the risk of pressure ulcers. Frequent repositioning helps alleviate pressure on vulnerable areas, improving circulation and preventing skin breakdown. This intervention is widely recommended to maintain skin integrity in at-risk clients.

Choice B reason:

Massaging the skin over bony prominences can cause tissue damage and increase the risk of pressure ulcers. Instead of promoting circulation, it can exacerbate skin breakdown and should be avoided as a preventive measure.

Choice C reason:

Positioning the client in high Fowler's is not specifically related to preventing pressure ulcers. High Fowler's position can help with respiratory issues but does not address pressure redistribution needed to prevent skin breakdown in vulnerable areas.

Choice D reason:

Applying cornstarch to keep sensitive skin areas dry is not an evidence-based intervention for pressure ulcer prevention. Cornstarch can create friction and irritation, potentially worsening skin integrity rather than preserving it.
