If a patient has dysfunction in the normal secretion of natriuretic hormones, which laboratory result should the nurse monitor?

Phosphorus.

Calcium.

Sodium.

Aldosterone.

Answer and Explanation

The Correct Answer is C

Choice A rationale:

Phosphorus. Rationale: Dysfunction in the normal secretion of natriuretic hormones is more likely to affect sodium and water balance, not phosphorus. Phosphorus levels are regulated by other mechanisms in the body and may not be directly influenced by natriuretic hormones. Choice A is incorrect.

Choice B rationale:

Calcium. Rationale: Calcium levels are not typically influenced by natriuretic hormones. Calcium regulation is primarily under the control of parathyroid hormone (PTH) and calcitonin. Dysfunction in natriuretic hormone secretion would not directly impact calcium levels. Choice B is incorrect.

Choice C rationale:

Sodium. Rationale: Natriuretic hormones, such as atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP), play a crucial role in regulating sodium balance in the body. If a patient has dysfunction in the normal secretion of these hormones, it can lead to sodium imbalance, potentially causing sodium retention and fluid overload. Therefore, monitoring sodium levels is essential in such cases. Choice C is the correct answer.

Choice D rationale:

Aldosterone. Rationale: Aldosterone is a hormone that primarily regulates sodium and potassium balance in the body. Dysfunction in natriuretic hormone secretion is not directly related to aldosterone. Therefore, monitoring aldosterone levels would not be the most appropriate action in this context. Choice D is incorrect. .

Correct Answer is A

Explanation

Choice A rationale:

Mitogens like angiotensin II and growth factors stimulate smooth muscle proliferation. Mitogens are substances that promote cell division and growth. Angiotensin II, for example, is known to stimulate smooth muscle cell proliferation, which can lead to conditions like vascular remodeling and hypertension.

Choice B rationale:

Endothelial injury is not directly stimulated by mitogens. Mitogens are more associated with cell growth and proliferation rather than causing injury to endothelial cells.

Choice C rationale:

Mitogens are not typically associated with cardiac muscle toxicity. Cardiac muscle toxicity can result from various factors like certain medications or diseases, but mitogens are not the primary cause of cardiac muscle toxicity.

Choice D rationale:

Mitogens are not directly related to the activation of phagocytes. Phagocytes are white blood cells involved in the immune response, and their activation is more related to infection or inflammation rather than mitogenic stimulation. Moving on to the last question.

A. Anemia. B. Smokes half a pack a day. C. BP 110/70. D. History of asthma.

Correct Answer is B

Explanation

Choice A rationale:

Anemia is not directly associated with endothelial injury in atherosclerosis. While anemia can lead to reduced oxygen delivery to tissues, it is not a primary factor in endothelial injury. Atherosclerosis is primarily linked to risk factors like smoking, hypertension, and hyperlipidemia.

Choice B rationale:

Smoking is a significant risk factor for atherosclerosis and can cause endothelial injury. Smoking introduces harmful chemicals into the bloodstream, leading to inflammation and damage to the inner lining of blood vessels (endothelium). This damage can promote the development of atherosclerotic plaques.

Choice C rationale:

Blood pressure of 110/70 is within the normal range, and while hypertension is a risk factor for atherosclerosis, this specific blood pressure measurement does not indicate endothelial injury.

Choice D rationale:

A history of asthma is not a direct risk factor for atherosclerosis or endothelial injury. While chronic inflammatory conditions can contribute to cardiovascular disease, asthma alone is not typically associated with atherosclerosis.
