A nurse is assisting with teaching a class about nutrients.
The nurse should include that which of the following is a function of fats?

Regulates nerve cell transmission.

Converts to sugar to provide energy.

Facilitates the absorption of vitamins.

Builds and repairs tissue.

Answer and Explanation

The Correct Answer is C

Choice A rationale

Regulating nerve cell transmission is primarily a function of electrolytes like sodium, potassium, and calcium, as well as neurotransmitters. While fats are components of nerve cell membranes, they do not directly regulate the transmission of nerve impulses.

Choice B rationale

Converting to sugar (glucose) to provide energy is the primary function of carbohydrates. While fats can be metabolized for energy, they are broken down into fatty acids and glycerol, not directly into glucose. Gluconeogenesis can convert glycerol to glucose, but this is a secondary energy pathway.

Choice C rationale

Fats are crucial for the absorption of fat-soluble vitamins (A, D, E, and K). These vitamins are lipophilic, meaning they dissolve in fats. Dietary fat is necessary in the small intestine to emulsify these vitamins, allowing them to be absorbed across the intestinal lining into the bloodstream.

Choice D rationale

Building and repairing tissue is the primary function of proteins, which are composed of amino acids. While fats are components of cell membranes and contribute to overall cell structure, they do not play the main role in tissue synthesis and repair.

Correct Answer is D

Explanation

Choice A rationale

While prostate enlargement is common in older men, it is not typically directly associated with bilateral gynecomastia. Gynecomastia primarily involves breast tissue enlargement due to hormonal imbalances, not glandular changes related to the prostate. Recommending prostate screening solely based on gynecomastia is not the most direct or scientifically sound approach.

Choice B rationale

Acknowledging gynecomastia as benign breast enlargement without further investigation might be premature. While some cases in older men are benign and related to aging, it can also be a symptom of underlying medical conditions or medication side effects that require evaluation. Dismissing it without investigation could miss a treatable cause.

Choice C rationale

A mammogram is a screening tool for breast cancer, which is rare in men but possible. However, gynecomastia is characterized by benign glandular tissue proliferation, distinct from the tissue changes typically associated with male breast cancer. While a physician might order one to rule out malignancy, it's not the initial recommended action based solely on the finding of bilateral gynecomastia.

Choice D rationale

Gynecomastia in men can result from various hormonal changes, including a decrease in testosterone levels relative to estrogen, or an increase in estrogen production. Certain medical conditions and medications can also disrupt hormonal balance. Recommending a physician visit to investigate potential underlying causes of hormonal changes is the most appropriate initial action to determine the etiology of the gynecomastia and guide further management.

A. "You are correct; mammography is a good replacement for BSEs.”. B. "You do not need to perform BSEs as long as a physician checks your breast annually.”. C. "While mammograms are effective, BSEs can help you become familiar with your breasts and notice changes between mammograms.”. D. "Mammograms are the only reliable way to detect breast cancer, so BSEs are unnecessary.”.

Correct Answer is C

Explanation

Choice A rationale

While mammography is a crucial tool for detecting breast cancer, particularly in women over 40, it is not a replacement for breast self-examination (BSE). Mammograms are radiographic images that can detect abnormalities, but BSE helps women become familiar with their own breasts and identify changes that may occur between mammograms.

Choice B rationale

Although annual clinical breast exams by a physician are important, they are not a substitute for monthly BSE. BSE allows women to regularly assess their breasts for any new lumps, changes in size or shape, skin thickening, or nipple discharge. These changes might occur between annual physician visits.

Choice C rationale

Mammograms are indeed effective in detecting breast cancer, often before a lump can be felt. However, BSE plays a vital role in increasing a woman's awareness of her breasts' normal texture and appearance. This familiarity enables her to notice subtle changes that may warrant further medical evaluation, complementing the benefits of mammography.

Choice D rationale

Mammograms are a highly reliable method for detecting breast cancer, especially in early stages. However, BSE is not unnecessary. It empowers women to take an active role in their breast health by promoting early detection of changes that might be indicative of cancer and can occur between scheduled mammograms.
