Nursing Elites

1. What causes an older female client's hair to turn gray?

• A. ''A loss of melanin occurs in the normal aging process.''
• B. ''The number of sweat glands and blood vessels decreases in the normal aging process.''
• C. ''The skin on the scalp becomes thin, causing moisture to escape.''
• D. ''It is caused by hereditary factors.''

Correct answer: A

Rationale: The correct answer is 'A loss of melanin occurs in the normal aging process.' Graying hair in older adults is primarily due to a decrease in the number of melanocytes responsible for providing pigment and hair color. This reduction in melanin production leads to gray hair. The other choices are incorrect. While it is true that the skin becomes thinner with aging and the number of sweat glands and blood vessels decreases, these changes are not directly related to graying hair. Additionally, hereditary factors can influence when graying starts, but they do not cause the graying of hair itself.

2. The LPN is about to give 100 mg Lopressor (metoprolol) to a client. Before administering the drug, they take the patient's vitals, which are as follows: Pulse: 58 Blood Pressure: 90/62 Respirations: 18/minute What action should the LPN take?

• A. Give the client half the prescribed dose and report the findings to the RN on duty.
• B. Give the client double the dose and report the findings to the RN on duty.
• C. Administer the drug and report the findings to the RN on duty.
• D. Hold the drug and report the findings to the RN on duty.

Correct answer: D

Rationale: Lopressor is given to treat hypertension, and a pulse of 58 and a blood pressure of 90/62 are considered low. To prevent the client from bottoming out, the drug should be held, and the findings reported to the RN, who should consult with the attending physician. LPNs should never adjust client dosing, as that is outside of their scope of practice. It is crucial to follow facility guidelines, which often recommend holding blood pressure medication at 60 bpm and a systolic pressure of 90 or less. By holding the drug and notifying the RN, the LPN ensures the client's safety and allows for appropriate assessment and decision-making by the healthcare team. Giving half the dose or double the dose without proper authorization can lead to serious complications and is considered unsafe practice.

3. Which of the following vaccines is not part of the regular schedule of immunizations for children?

• A. DTaP
• B. MMR
• C. Hib
• D. hepatitis A

Correct answer: D

Rationale: The correct answer is hepatitis A. DTaP, MMR, and Hib are all part of the regular schedule of immunizations for children to protect them against diseases like diphtheria, tetanus, pertussis, measles, mumps, rubella, and Haemophilus influenzae type b. Hepatitis A vaccine is not included in the routine childhood immunization schedule but may be recommended in certain situations or regions where the disease is more prevalent. Hepatitis A is generally considered an optional vaccine for children but can be administered based on specific risk factors or regional guidelines.

4. A client has just returned from surgery where a femoral-popliteal bypass was performed. The nurse has assessed the client and is unable to feel a pulse at either the dorsalis pedis or the posterior tibial sites of the left foot. The foot feels warm, and the color is pink. What action should the nurse perform next to prevent ischemia?

• A. Notify the physician immediately
• B. Obtain a Doppler device to check for pulses, and notify the physician if they are still absent
• C. Wait 30 minutes and recheck the pulses
• D. Document the finding

Correct answer: B

Rationale: The nurse should immediately obtain a Doppler device and recheck the pulses. The dorsalis pedis and posterior tibial pulses can be difficult to assess and might need to be verified with a Doppler device. Since the client just had surgery with a risk of arterial insufficiency, close monitoring is crucial. If pulses are not palpable, it indicates an emergent situation requiring immediate physician notification. Waiting 30 minutes before reassessment could lead to foot ischemia. While documenting findings is essential, it should follow pulse confirmation or necessary interventions to ensure the client's foot viability.

5. A nurse is preparing to auscultate a client's breath sounds. To assess vesicular breath sounds, the nurse places the stethoscope over which area?

• A. Major bronchi
• B. The xiphoid process
• C. The trachea and larynx
• D. The peripheral lung fields

Correct answer: D

Rationale: To assess vesicular breath sounds, the nurse should place the stethoscope over the peripheral lung fields. Vesicular breath sounds are heard in these areas where air flows through the smaller bronchioles and alveoli. Bronchovesicular breath sounds, not vesicular, are heard over the major bronchi. Bronchial (tracheal) breath sounds are heard over the trachea and larynx, not vesicular sounds. Breath sounds are not heard over the xiphoid process, making it an incorrect choice.
