During a fecal impaction removal, an older client complains of feeling dizzy and cold.
Which intervention should the nurse implement?

Choice A rationale:

Aspirin is not typically contraindicated in a client who has taken sildenafil unless there are specific contraindications or allergies. Aspirin is often used in the management of acute chest pain to help prevent blood clot formation.

Choice B rationale:

Heparin is not contraindicated solely because the client has taken sildenafil. Heparin is an anticoagulant commonly used in various clinical settings, including the management of certain cardiac conditions.

Choice C rationale:

Morphine is not necessarily contraindicated based solely on the client's use of sildenafil. Morphine can be used to relieve chest pain in some cases of acute coronary syndrome. However, its use should be carefully evaluated based on the client's overall clinical presentation.

Choice D rationale:

Nitroglycerin should be withheld in this scenario. Sildenafil is a medication used to treat erectile dysfunction and pulmonary arterial hypertension. It can potentiate the vasodilatory effects of nitroglycerin, leading to a severe drop in blood pressure. Concomitant use of nitroglycerin and sildenafil is contraindicated due to the risk of significant hypotension, which can be life-threatening.

Choice A rationale:

Hyperglycemia is a key symptom of DKA. It occurs when there is an insufficient amount of insulin in the body to allow glucose to enter cells for use as energy. As a result, the body begins to break down fat for fuel, leading to the production of ketones and causing blood glucose levels to rise1. Normal blood glucose levels are between 4.0 to 6.0 mmol/L when fasting and up to 7.8 mmol/L two hours after eating2.

Choice B rationale:

Ketonuria, or the presence of ketones in the urine, is another symptom of DKA. When the body breaks down fat for energy, ketones are produced. If too many ketones build up in the blood, they can spill over into the urine1.

Choice C rationale:

Metabolic acidosis occurs in DKA due to the accumulation of ketones in the blood. Ketones are acidic, and when they build up in the blood, they cause the blood to become more acidic, leading to metabolic acidosis1.

Choice D rationale:

Hypokalemia is not a symptom of DKA. In fact, patients with DKA often have high potassium levels in their blood at presentation because acidosis causes potassium to move from inside the cells into the bloodstream1. However, during treatment for DKA, when insulin is administered and acidosis is corrected, potassium moves back into the cells and can lead to low potassium levels or hypokalemia1.

Choice E rationale:

Dehydration is a common symptom of DKA. High blood glucose levels lead to increased urination as the body tries to get rid of the excess glucose. This can result in dehydration1.

Choice F rationale:

Kussmaul respirations are a type of hyperventilation that occurs in DKA as the body tries to get rid of excess acids (ketones) through the lungs by breathing rapidly and deeply1.
