Nursing Elites

1. A public health nurse is managing several projects for the community. Which of the following interventions should the nurse identify as a primary prevention strategy?

• A. Teaching parenting skills to expectant mothers and their partners.
• B. Conducting mental health screenings at the local community center
• C. Referring clients with obesity to community exercise programs
• D. Providing crisis intervention through a mobile counseling unit

Correct answer: A

Rationale: The correct answer is teaching parenting skills to expectant mothers and their partners. This intervention is a primary prevention strategy aimed at educating individuals before a problem or condition develops. By teaching parenting skills, the nurse is promoting healthy behaviors and relationships, which can prevent future issues. The other options involve secondary or tertiary prevention strategies by identifying and treating existing conditions or providing interventions after a problem has occurred.

2. What is the primary purpose of handwashing?

• A. To promote hand circulation
• B. To prevent the transfer of microorganisms
• C. To avoid touching the client with a dirty hand
• D. To provide comfort

Correct answer: B

Rationale: The primary purpose of handwashing is to prevent the transfer of microorganisms. Proper hand hygiene helps reduce the risk of spreading harmful bacteria and viruses, thus promoting overall health and preventing infections. Choice A is incorrect as handwashing primarily focuses on cleanliness rather than promoting circulation. Choice C is incorrect as it implies that the main concern is avoiding client discomfort rather than preventing infection. Choice D is incorrect as while handwashing can be comforting in some situations, its primary purpose is not to provide comfort but to maintain hygiene.

3. A healthcare professional is reviewing ABG laboratory results of a client who is in respiratory distress. The results are pH 7.47, PaCO2 32 mm Hg, and HCO3 22 mm Hg. The healthcare professional should recognize that the client is experiencing which of the following acid-base imbalances?

• A. Respiratory acidosis
• B. Respiratory alkalosis
• C. Metabolic acidosis
• D. Metabolic alkalosis

Correct answer: B

Rationale: The ABG results show a high pH (alkalosis) along with low PaCO2 and normal HCO3 levels, indicating respiratory alkalosis. In this condition, there is excessive loss of carbon dioxide (as seen by the low PaCO2) leading to a decrease in carbonic acid concentration and subsequent increase in pH. Metabolic acidosis or alkalosis would involve primary changes in bicarbonate levels, which are not predominant in this case.

4. Mrs. Mitchell has been given a copy of her diet. The nurse discusses the foods allowed on a 500-mg low sodium diet. These include:

• A. A ham and Swiss cheese sandwich on whole wheat bread
• B. Mashed potatoes and broiled chicken
• C. A tossed salad with oil and vinegar and olives
• D. Chicken bouillon

Correct answer: B

Rationale: The correct answer is B: Mashed potatoes and broiled chicken. Both mashed potatoes and broiled chicken are typically low in sodium content, making them suitable choices for a 500-mg low sodium diet. The other options, such as a ham and Swiss cheese sandwich on whole wheat bread, a tossed salad with oil and vinegar and olives, and chicken bouillon, may contain higher amounts of sodium and are not typically recommended for a low sodium diet.

5. Which hormone is secreted by the Islets of Langerhans?

• A. Progesterone
• B. Testosterone
• C. Insulin
• D. Hemoglobin

Correct answer: C

Rationale: Insulin is the correct answer. It is the hormone secreted by the Islets of Langerhans in the pancreas. These specialized cells regulate blood sugar levels by releasing insulin in response to high blood glucose levels. Insulin aids in glucose absorption by cells, lowering blood sugar levels. Progesterone, testosterone, and hemoglobin are not secreted by the Islets of Langerhans and do not play a role in blood sugar regulation.
