Nursing Elites

1. What effect can medication bound to protein have?

• A. reduced drug availability
• B. limited distribution of the drug to receptor sites
• C. less availability to produce desired medicinal effects
• D. decreased metabolism of the drug by the liver

Correct answer: C

Rationale: Medication bound to protein leads to less availability to produce desired medicinal effects because only unbound drugs can interact with active receptor sites. If a drug is bound to protein, it cannot bind with a receptor site, reducing its effectiveness. Choice A is incorrect because binding to protein reduces drug availability. Choice B is incorrect because distribution to receptor sites is ineffective if the drug is bound to protein. Choice D is incorrect because metabolism does not occur until the drug is removed from the protein molecule by the liver, allowing the protein to return to circulation.

2. During a well-baby examination, the nurse measures the head circumference, and it is the same as the chest circumference. On the basis of this measurement, what action should the nurse take?

• A. Document these measurements in the infant's health care record.
• B. Tell the mother that the infant is growing faster than expected.
• C. Suggest to the health care provider that a skull x-ray be performed.
• D. Report the presence of hydrocephalus to the health care provider.

Correct answer: A

Rationale: The head circumference growth rate during the first year is approximately 0.4 inches (1 cm) per month. By 10 to 12 months of age, the infant's head and chest circumferences are equal. In this case, where the head circumference matches the chest circumference, it is a normal finding in infants around 10-12 months. Therefore, the most appropriate action is to document these measurements in the infant's health care record. Suspecting hydrocephalus or suggesting a skull x-ray would be premature and not indicated based on this measurement. Similarly, telling the mother that the infant is growing faster than expected is not accurate and could cause unnecessary concern.

3. When preparing to listen to a client's breath sounds, what technique should a nurse use?

• A. Ask the client to sit and lean forward slightly, with the arms resting comfortably across the lap.
• B. Listen to the right lung first, then the left lung, moving from top to bottom systematically.
• C. Ask the client to take deep breaths through the mouth.
• D. Use the diaphragm of the stethoscope, holding it firmly against the client's chest.

Correct answer: D

Rationale: When preparing to listen to a client's breath sounds, a nurse should ask the client to sit and lean forward slightly, with the arms resting comfortably across the lap. The client should be instructed to breathe through the mouth a little more deeply than usual but to stop if feeling dizzy. The nurse should use the flat diaphragm end-piece of the stethoscope, holding it firmly on the chest wall. By using the diaphragm, the nurse can listen for at least one full respiration in each location, moving from side to side to compare sounds. This technique ensures a systematic and thorough assessment of lung sounds. Choice A is correct as it includes the proper positioning of the client and specifies the use of the diaphragm of the stethoscope. Choice B is incorrect as both lungs should be auscultated systematically, starting from the top and moving down. Choice C is incorrect as deep breaths, not shallow ones, are recommended for an accurate assessment of breath sounds.

4. When performing an eye examination, which area can a healthcare provider best visualize using an ophthalmoscope?

• A. Iris
• B. Cornea
• C. Optic disc
• D. Conjunctiva

Correct answer: C

Rationale: An ophthalmoscope is a tool used to visualize the internal structures of the eye during an examination. The optic disc, located on the internal surface of the retina, can be best visualized using an ophthalmoscope. The iris, cornea, and conjunctiva are superficial structures that can be examined without the need for an ophthalmoscope. Therefore, the correct answer is the optic disc. Choices A, B, and D are incorrect because they are external structures that can be examined directly without the use of an ophthalmoscope.

5. When administering a nasal spray medication, what should the client do before the medication is administered?

• A. The client should blow their nose gently before the medication is administered.
• B. The medication should be sprayed into the nostril.
• C. The medication should be administered as the client inhales.
• D. The client should sit upright when the medication is administered.

Correct answer: A

Rationale: The correct answer is that the client should blow their nose gently before the medication is administered. This step helps clear the nasal passages, ensuring that the medication can reach its intended target. Choice B is incorrect as the nasal spray should be directed into the nostril, not just in front of the nose. Administering the medication as the client inhales (Choice C) is crucial to ensure proper delivery, as it helps the medication reach the desired areas. Choice D is incorrect because the client should be sitting upright, not lying flat, when administering nasal spray medication to allow for better absorption and prevent the medication from flowing out.
