A patient who smokes reports chest pain while at rest.
Which condition would the nurse suspect the patient is experiencing?

Silent ischemia.

Angina decubitus.

Prinzmetal angina.

Chronic stable angina.

Answer and Explanation

The Correct Answer is C

Choice A rationale:

Silent ischemia refers to a lack of oxygen to the heart that doesn't cause symptoms like chest pain. It is often diagnosed during an electrocardiogram (ECG) done for other reasons. The patient in this scenario is experiencing chest pain, so silent ischemia is not the correct choice.

Choice B rationale:

Angina decubitus refers to chest pain that occurs while lying down and is relieved by standing or sitting. The patient in this scenario is experiencing chest pain at rest, which is not characteristic of angina decubitus.

Choice D rationale:

Chronic stable angina is chest pain or discomfort that typically occurs with activity or stress and is relieved by rest or nitroglycerin. The patient in this scenario is experiencing chest pain at rest, which is not characteristic of chronic stable angina.

Correct Answer is B

Explanation

Choice A rationale:

Flossing using thick tape floss can cause trauma to the gums and may lead to bleeding in patients with thrombocytopenia. Patients with low platelet counts are at risk of excessive bleeding from minor injuries, and using thick tape floss could potentially harm the gums and exacerbate bleeding.

Choice B rationale:

Shaving using an electric razor is a safe option for patients with thrombocytopenia. Electric razors do not pose a significant risk of cuts or nicks, reducing the likelihood of bleeding, which is crucial for patients with low platelet counts.

Choice C rationale:

Wearing flip-flops to go walking may not be the safest option for a patient with thrombocytopenia. If the patient accidentally stubs their toe or injures their foot while wearing flip-flops, it could lead to bleeding. Closed-toe, comfortable shoes provide better protection against foot injuries.

Choice D rationale:

Brushing using a stiff-bristle toothbrush can be harmful to the gums, especially for patients with thrombocytopenia. Stiff-bristle toothbrushes can cause gum irritation and bleeding. Patients with low platelet counts should use a soft-bristle toothbrush to minimize the risk of gum injury.

A. Eliminating excess H+. B. Excreting excess water. C. Eliminating excess CO2. D. Reabsorbing additional HCO3-. E. Reabsorbing additional sodium ions.

Correct Answer is ["A","D"]

Explanation

Choice A rationale:

Eliminating excess H+ ions (hydrogen ions) is a primary mechanism the kidneys use to buffer acidosis. In acidosis, there is an excess of hydrogen ions in the body, leading to a decrease in pH. The kidneys help regulate the body's pH by excreting hydrogen ions to lower acidity.

Choice B rationale:

Excreting excess water is not a specific acid-base mechanism related to acidosis. While maintaining proper hydration is important for overall health, it does not directly influence the body's acid-base balance in the context of acidosis.

Choice C rationale:

Eliminating excess CO2 is primarily a respiratory mechanism, not a kidney function. CO2 elimination is more related to the lungs' ability to regulate the body's pH by adjusting respiratory rate and depth.

Choice D rationale:

Reabsorbing additional HCO3- ions (bicarbonate ions) is a renal mechanism to buffer acidosis. Bicarbonate ions act as a base and can neutralize excess hydrogen ions, raising the pH of the body fluids.

Choice E rationale:

Reabsorbing additional sodium ions is not a specific acid-base mechanism related to acidosis. While sodium ions are important for various physiological processes, they do not play a direct role in buffering acidosis.
