Walden University 2026 | Most Tested Questions & Verified
Answers | Graded A+
Describe how sodium and water accumulation affects cellular function in
injured cells.
Sodium accumulation enhances cellular metabolism, improving
function.
Sodium and water accumulation has no effect on cellular function.
Water accumulation causes cellular dehydration, leading to cell death.
Sodium and water accumulation leads to cellular swelling, disrupting
normal cellular function and potentially causing cell damage.
1. Describe how hyperthyroidism affects weight regulation in the body.
Hyperthyroidism typically leads to weight loss due to increased
metabolism.
Hyperthyroidism causes weight gain by slowing down metabolism.
Hyperthyroidism has no effect on weight regulation.
Hyperthyroidism results in fluctuating weight without a clear pattern.
2. What is the definition of pulmonic regurgitation?
Pulmonic regurgitation is the backflow of blood from the pulmonary
artery into the right ventricle due to improper closure of the
pulmonic valve.
Pulmonic regurgitation is the leakage of blood from the left ventricle
into the aorta.
Pulmonic regurgitation is the complete blockage of blood flow from
the right ventricle to the pulmonary artery.
, Pulmonic regurgitation is the narrowing of the pulmonary valve,
restricting blood flow.
3. If a patient with cirrhosis has elevated cholesterol levels, what dietary
recommendation should the nurse provide?
The nurse should recommend a diet low in saturated fats and
cholesterol.
The nurse should advise the patient to avoid all fats completely.
The nurse should suggest a high-fat diet to boost energy.
The nurse should encourage increased intake of red meats.
4. What is the primary role of anti-diuretic hormone (ADH) in the body?
To enhance calcium absorption in the intestines.
To regulate water balance by promoting water reabsorption in the
kidneys.
To stimulate the production of red blood cells.
To increase blood glucose levels.
5. Describe how hypertension affects cardiac output and total peripheral
resistance in the cardiovascular system.
Hypertension decreases both cardiac output and total peripheral
resistance.
Hypertension typically leads to an increase in total peripheral
resistance, which can decrease cardiac output if the heart cannot
compensate.
Hypertension has no significant impact on cardiac output or total
peripheral resistance.
, Hypertension increases cardiac output while decreasing total
peripheral resistance.
6. What is a common effect of hyperthyroidism on the body's metabolism?
Decreased metabolism
Stable metabolism
Increased metabolism
No effect on metabolism
7. If a patient has a dysfunction in the hypothalamus affecting hormone release,
what potential impact could this have on the anterior pituitary gland's
function?
It could lead to abnormal levels of anterior pituitary hormones due
to lack of regulatory signals.
It would only affect the secretion of thyroid-stimulating hormone
(TSH).
It would have no effect on anterior pituitary hormone levels.
It would enhance the secretion of all anterior pituitary hormones.
8. If a 50-year-old male with Huntington disease has two children, what is the
probability that each child will inherit the disorder?
75%
25%
100%
50%
, 9. Describe the significance of TSH and T4 levels in the diagnosis of thyroid
disorders.
High T4 levels always indicate hypothyroidism regardless of TSH
levels.
TSH levels are irrelevant to thyroid function, while T4 levels alone
determine thyroid health.
TSH and T4 levels are only relevant in diagnosing diabetes, not
thyroid disorders.
Abnormal levels of TSH and T4 indicate hypo/hyperthyroidism, with
high TSH suggesting hypothyroidism and low TSH indicating
hyperthyroidism.
10. Myocarditis is an inflammatory disorder that
Results in hypertrophy of all four chambers of the heart
Impairs left ventricular filling
is most commonly associated with streptococcal infections
Often leads to dilated cardiomyopathy
11. What is the genetic principle that explains the variability of symptoms in
neurofibromatosis?
Incomplete dominance
Codominance
Genetic drift
Variable expressivity
