Nursing Elites

1. 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 water and one part concentrate.
• D. When using powdered formula, mix two parts water and one part powder.

Correct answer: A

Rationale: The correct answer is to use the defrost setting on microwave ovens to warm bottles. It is essential for parents to be cautious when warming bottles in a microwave oven to prevent superheating of the milk. Choosing the defrost setting and checking the formula temperature before giving it to the baby helps avoid burns. Discarding partially used bottles after 24 hours when refrigerating formula is crucial as it reduces the risk of harmful bacterial growth. Mixing formula concentrate with water in a 1:1 ratio of one part concentrate to one part water ensures proper dilution of the formula. On the other hand, powdered formula should be mixed following the package instructions, typically using two parts water to one part powder. This accurate mixing ratio provides the necessary balance of nutrients for the baby. Adding fresh formula to partially used bottles can introduce pathogens that may harm the infant, underscoring the importance of discarding partially used bottles and preparing formula correctly. Therefore, options B, C, and D are incorrect as they do not address the safe and proper ways to feed a newborn effectively.

2. 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: A

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.

3. A client is given an opiate drug for pain relief following general anesthesia. The client becomes extremely somnolent with respiratory depression. The physician is likely to order the administration of:

• A. naloxone (Narcan)
• B. labetalol (Normodyne)
• C. neostigmine (Prostigmin)
• D. thiothixene (Navane)

Correct answer: A

Rationale: In this scenario, the client is experiencing respiratory depression due to opiate overdose. Naloxone (Narcan) is an opioid antagonist that can rapidly reverse the effects of opiates by competitively binding to opioid receptors and displacing the opiates. This action can restore normal respiration and consciousness. Labetalol (Normodyne) is a non-selective beta-blocker used to manage hypertension, not opioid-induced respiratory depression. Neostigmine (Prostigmin) is a cholinesterase inhibitor used to reverse neuromuscular blockade, not opioid overdose. Thiothixene (Navane) is an antipsychotic medication used to manage psychotic disorders, not opioid toxicity.

4. When inspecting the ears for cerumen impaction, the nurse checks for which finding?

• A. Redness and swelling of the tympanic membrane
• B. An external auditory canal that is longer than normal
• C. The presence of edema in the external auditory canal
• D. A yellowish or brownish waxy material in the external auditory canal

Correct answer: D

Rationale: When inspecting the ears for cerumen impaction, the nurse should look for a yellowish or brownish waxy material in the external auditory canal. Cerumen, also known as ear wax, is a secretion that can become impacted due to various reasons. It is produced by the vestigial apocrine sweat glands in the external ear canal. Cerumen may partially obscure the eardrum or totally occlude the ear canal. The other options, redness and swelling of the tympanic membrane, an external auditory canal that is longer than normal, and the presence of edema in the external auditory canal, are not indicative findings of cerumen impaction.

5. Distribution of a drug to various tissues depends on the amount of cardiac output to each type of tissue. Which tissue would receive the highest amount of cardiac output and thus the highest amount of a drug?

• A. skin
• B. adipose tissue
• C. skeletal muscle
• D. myocardium

Correct answer: D

Rationale: The tissue that would receive the highest amount of cardiac output and thus the highest amount of a drug is the myocardium. Highly perfused tissues include vital organs like the brain, heart, kidneys, adrenal glands, and liver. The myocardium, being part of the heart, receives a significant amount of cardiac output. Choices A (skin) and B (adipose tissue) are poorly perfused tissues and would not receive high amounts of cardiac output. Choice C (skeletal muscle) is also less perfused compared to the myocardium.
