1. When preparing to assist the healthcare provider in examining a client’s skin with the use of a Wood light, what action should the nurse perform?
- A. Darken the room
- B. Obtain informed consent from the client
- C. Obtain a scalpel and a slide for diagnostic evaluation
- D. Obtain medication to anesthetize the skin area before proceeding with the examination
Correct answer: Darken the room
Rationale: When using a Wood light during a skin examination, the room should be darkened to enhance the visibility of fluorescence. The Wood light emits long-wavelength ultraviolet light, highlighting certain skin conditions. Darkening the room aids in better visualization. Obtaining informed consent is a crucial aspect of healthcare but not directly related to using a Wood light. Obtaining a scalpel and a slide is unnecessary for a noninvasive Wood light examination. Anesthetizing the skin area is not required as the procedure is painless and noninvasive.
2. 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: Use the defrost setting on microwave ovens to warm bottles.
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.
3. An allergic reaction is classified as what type of pharmacological effect?
- A. a therapeutic effect
- B. a side effect
- C. an adverse effect
- D. an incompatibility
Correct answer: an adverse effect
Rationale: An allergic reaction is classified as an adverse effect because it is an unintended response to a medication that requires treatment. A side effect is an undesired but somewhat expected reaction to a drug that does not necessarily need intervention. Incompatibility refers to an unsuitable combination of substances that leads to an adverse effect. A therapeutic effect is the desired and intended outcome of a medication.
4. What is the primary nutritional deficiency of concern for a strict vegetarian?
- A. vitamin C
- B. vitamin B12
- C. vitamin E
- D. magnesium
Correct answer: vitamin B12
Rationale: Vitamin B12 is the primary nutritional deficiency of concern for a strict vegetarian. While all mentioned vitamins are essential for overall health, vitamin B12 is particularly important for vegetarians as it is mainly found in animal products. A strict vegetarian diet may lack sufficient vitamin B12 intake, leading to potential health issues like anemia and neurological problems. Vitamin C deficiency is more commonly associated with scurvy, which is preventable with a diet rich in fruits and vegetables. Vitamin E deficiency is rare and usually only seen in specific medical conditions. Magnesium deficiency is not typically a primary concern for strict vegetarians as magnesium can be obtained from a variety of plant-based sources.
5. How often should the intravenous tubing on total parenteral nutrition solutions be changed?
- A. every 24 hours
- B. every 36 hours
- C. every 48 hours
- D. every 72 hours
Correct answer: every 24 hours
Rationale: The correct answer is to change the intravenous tubing on total parenteral nutrition solutions every 24 hours. This frequency is necessary due to the high risk of bacterial growth associated with TPN solutions. Changing the tubing every 24 hours helps prevent contamination and bloodstream infections. Choices B, C, and D are incorrect because waiting longer intervals increases the risk of introducing harmful bacteria into the patient's system, leading to potentially severe complications.
