Nursing Elites

1. A client complains that her skin is redder than normal. The nurse notes the client's skin, documents hyperemia, and explains to the client that this condition is caused by which factor?

• A. Constriction of the underlying blood vessels
• B. An increased amount of bilirubin in the blood
• C. Increased perfusion of the surrounding tissues
• D. Excess blood in the dilated superficial capillaries

Correct answer: D

Rationale: Hyperemia is an excess of blood in a part of the body. The skin over a hyperemic area usually becomes reddened or warm. The condition is caused by increased blood flow, local relaxation of arterioles, or obstruction of the outflow of blood from an area. Choice A is incorrect because constriction of blood vessels would lead to decreased blood flow, not excess blood. Choice B is incorrect as an increased amount of bilirubin in the blood is related to jaundice, not hyperemia. Choice C is incorrect because increased perfusion of the surrounding tissues would cause redness, not hyperemia.

2. The client has an order for an IV piggyback of Ceftriaxone 750mg in 50mL D5W to run over 30 minutes. What is the appropriate drip rate?

• A. 100 mL/hr
• B. 150 mL/hr
• C. 200 mL/hr
• D. 50 mL/hr

Correct answer: A

Rationale: To calculate the drip rate, you need to convert the time from minutes to hours. The formula is (Volume to be infused / Time for infusion in minutes) x (60 minutes / 1 hour). Substituting the values, (50 mL / 30 min) x (60 min / 1 hr) = 100 mL/hr. Therefore, the appropriate drip rate is 100 mL/hr. Choices B, C, and D are incorrect as they do not match the calculated drip rate. Option A, 100 mL/hr, is the correct drip rate for administering Ceftriaxone 750mg in 50mL D5W over 30 minutes.

3. A pregnant client asks how she can prevent getting Group B Strep. What is the LPN's best response?

• A. You cannot prevent getting Group B Strep; you can only treat it.
• B. You should have your partner wear a condom every time you have intercourse.
• C. You should be extra vigilant about hand-washing, especially in the third trimester.
• D. The Group B Strep vaccine is the only proven way to prevent the disease.

Correct answer: A

Rationale: The best response for the LPN to provide to a pregnant client concerned about preventing Group B Strep is that it cannot be prevented, only treated. Group B Strep is a normal flora found in the vagina, rectum, and intestines of about 25% of women and is not a sexually transmitted disease. Testing for Group B Strep is done in each pregnancy, usually around 35-37 weeks. If a woman tests positive, antibiotics are administered during labor to reduce the risk of complications for both the mother and the baby. Choice A is the correct answer as Group B Strep cannot be prevented but only treated. Choice B is incorrect; condom use does not prevent Group B Strep. Choice C is not the best response as hand-washing is important for general hygiene but does not specifically prevent Group B Strep. Choice D is incorrect as there is no vaccine available to prevent Group B Strep.

4. The nurse is teaching parents of a newborn about feeding their infant. Which of the following instructions should the nurse include?

• A. Use the defrost setting on microwave ovens to warm bottles.
• B. When refrigerating formula, discard partially used bottles after 24 hours.
• C. When using formula concentrate, mix one part concentrate and two parts water.
• D. If a portion of one bottle is left for the next feeding, discard it.

Correct answer: B

Rationale: The correct answer is to use the defrost setting on microwave ovens to warm bottles. It is crucial to be cautious when heating bottles in a microwave to prevent milk from becoming superheated. The defrost setting is recommended, and the formula's temperature should always be checked before feeding the baby. Choice B, which advises to discard partially used bottles of refrigerated formula after 24 hours, is also correct. This is important to prevent the introduction of pathogens by the baby into the formula. Choice C, recommending mixing one part formula concentrate with two parts water, is essential for ensuring the correct dilution. Choice D, suggesting to discard any remaining portion of a bottle for the next feeding, is incorrect. It is not necessary to discard the remaining portion if it has been refrigerated promptly and used within a safe time frame. Adding fresh formula to a partially used bottle is not recommended, as it can lead to the growth of pathogens that may be transferred to the new formula.

5. A nurse is reviewing the medical record of an older client with presbycusis. Which finding would the nurse expect to note in the client's record?

• A. Difficulty hearing whispered words in the voice test
• B. Improved hearing ability during conversational speech
• C. Unilateral conductive hearing loss
• D. Difficulty hearing low-pitched tones

Correct answer: A

Rationale: Presbycusis, a sensorineural hearing loss, is the most common form of hearing loss in older adults. Typically, the loss is bilateral, resulting in difficulty hearing high-pitched tones. The condition is revealed when the client has difficulty hearing whispered words in the voice test and consonants during conversational speech. Choice A is correct because it reflects the expected finding in presbycusis. Choices B, C, and D are incorrect because presbycusis does not result in improved hearing ability during conversational speech, unilateral conductive hearing loss, or difficulty hearing low-pitched tones.
