Nursing Elites

1. The nurse discovers that an elderly client with no history of cardiac or renal disease has an elevated serum magnesium level. To further investigate the cause of this electrolyte imbalance, what information is most important for the nurse to obtain from the client's medical history?

• A. Frequency of laxative use for chronic constipation
• B. Dietary intake of magnesium-rich foods
• C. Use of magnesium-containing supplements
• D. History of alcohol use

Correct answer: A

Rationale: The correct answer is A. Frequent use of magnesium-containing laxatives can lead to hypermagnesemia, particularly in elderly clients. Option B, dietary intake of magnesium-rich foods, may contribute to elevated serum magnesium levels but is less likely the cause in this scenario. Option C, the use of magnesium-containing supplements, can also contribute to hypermagnesemia but is not as common in elderly clients without a history of using such supplements. Option D, history of alcohol use, is less relevant to the development of elevated serum magnesium levels compared to laxative use for chronic constipation.

2. After placing a stethoscope as seen in the picture, the nurse auscultates S1 and S2 heart sounds. To determine if an S3 heart sound is present, what action should the nurse take first?

• A. Slide the stethoscope across the sternum.
• B. Move the stethoscope to the mitral site.
• C. Listen with the bell at the same location.
• D. Observe the cardiac telemetry monitor.

Correct answer: C

Rationale: The nurse uses the bell of the stethoscope to hear low-pitched sounds such as S3 and S4. To determine if an S3 heart sound is present, the nurse should listen at the same location using the bell first. This allows for the accurate identification of low-pitched sounds. Moving the stethoscope across the sternum (Choice A) or to the mitral site (Choice B) would not be the initial actions to assess for an S3 heart sound. Observing the cardiac telemetry monitor (Choice D) is not relevant for assessing S3 heart sounds, as it does not provide direct auscultation of heart sounds.

3. A client who is taking an oral dose of a tetracycline complains of gastrointestinal upset. What snack should the nurse instruct the client to take with the tetracycline?

• A. Fruit-flavored yogurt
• B. Cheese and crackers
• C. Cold cereal with skim milk
• D. Toasted wheat bread and jelly

Correct answer: D

Rationale: The correct answer is D: Toasted wheat bread and jelly. Dairy products decrease the effect of tetracycline, so the nurse should instruct the client to avoid them. Toast, which contains no dairy products, may help decrease gastrointestinal symptoms. Choices A, B, and C contain dairy products, which should be avoided when taking tetracycline.

4. The mother of a one-month-old boy born at home brings the infant to his first well-baby visit. She mentions that he was born two weeks after his due date and is a 'good, quiet baby' who almost never cries. To assess for hypothyroidism, what question is most important for the nurse to ask the mother?

• A. Has your son had any immunizations yet?
• B. Is your son sleepy and difficult to feed?
• C. Are you breastfeeding or bottle feeding your son?
• D. Were any relatives born with birth defects?

Correct answer: B

Rationale: The correct answer is B. Sleepiness and difficulty feeding are key signs of congenital hypothyroidism, which requires early diagnosis and treatment. Asking about immunizations (choice A) is important but not directly related to assessing hypothyroidism. The feeding method (choice C) is relevant for overall health but not specific to hypothyroidism. Inquiring about relatives with birth defects (choice D) is not the most crucial question to assess hypothyroidism in this scenario.

5. The charge nurse observes a new nurse preparing to insert an intravenous (IV) catheter. The new nurse has gathered supplies, including intravenous catheters, an intravenous insertion kit, and a 4x4 sterile gauze dressing to cover and secure the insertion site. What action should the charge nurse take?

• A. Instruct the nurse to use a transparent dressing over the site
• B. Allow the new nurse to proceed with the procedure
• C. Assist the new nurse with the insertion
• D. Replace the 4x4 gauze with a larger dressing

Correct answer: A

Rationale: The correct answer is to instruct the nurse to use a transparent dressing over the site. Transparent dressings allow for continuous observation of the IV site, reducing the risk of complications. Choice B is incorrect because the charge nurse should intervene to ensure the new nurse follows best practices. Choice C is incorrect as the charge nurse should not just assist but provide guidance on the correct procedure. Choice D is incorrect because the size of the dressing is not the issue; it's the type of dressing that allows for better observation.
