Nursing Elites

1. A client's arterial blood gas results show a pH of 7.3 and a PaCO2 of 50 mm Hg. The client is experiencing which of the following acid-base imbalances?

• A. Metabolic acidosis
• B. Metabolic alkalosis
• C. Respiratory acidosis
• D. Respiratory alkalosis

Correct answer: C

Rationale: In respiratory acidosis, there is an excess of carbon dioxide (PaCO2 > 45 mm Hg) leading to a decrease in pH (<7.35). The given values of a pH of 7.3 and PaCO2 of 50 mm Hg indicate respiratory acidosis. Metabolic acidosis involves a primary decrease in bicarbonate levels with a compensatory decrease in PaCO2 to maintain balance. Metabolic alkalosis is characterized by elevated pH and bicarbonate levels. Respiratory alkalosis is marked by low PaCO2 and increased pH levels.

2. A nurse is assessing a client for a suspected anaphylactic reaction following a CT scan with contrast media. For which of the following client findings should the nurse intervene first?

• A. Urticaria
• B. Stridor
• C. Vomiting
• D. Hypotension

Correct answer: B

Rationale:

3. When orienting a new client and family to the inpatient unit, what information should the nurse provide to help the client promote their own safety?

• A. Encourage the client and family to be active partners.
• B. Instruct the client to monitor hand hygiene in caregivers.
• C. Offer the family the opportunity to stay with the client.
• D. Advise the client to always wear their armband.

Correct answer: A

Rationale: Encouraging the client and family to be active partners in their healthcare is crucial for promoting safety. When clients and families actively participate, they are more likely to advocate for themselves, ask questions, and be engaged in their care, leading to better outcomes and reduced risks.

4. During a home visit to an older client living alone post-coronary artery bypass graft, what finding prompts the nurse to consider additional referrals?

• A. Dirty carpets requiring vacuuming
• B. Expired food found in the refrigerator
• C. Outdated medications stored in the kitchen
• D. Presence of multiple cats in the home

Correct answer: B

Rationale: The presence of expired food in the refrigerator is concerning as it raises safety issues for the client and indicates potential financial constraints preventing them from buying fresh food. The nurse should consider referring the client to services like Meals on Wheels or other home-based food programs to address this issue and ensure the client's nutritional needs are met.

5. A client with asthma has developed viral pharyngitis. Which of the following findings should the nurse expect?

• A. Petechiae on the chest and abdomen
• B. WBC 16,000/mm3
• C. Negative throat culture
• D. Severe hyperemia of pharyngeal mucosa

Correct answer: C

Rationale: Viral pharyngitis is typically caused by a virus, not bacteria, so a negative throat culture is an expected finding. The presence of petechiae on the chest and abdomen (Choice A) is not a common manifestation of viral pharyngitis. Elevated WBC count (Choice B) is more indicative of a bacterial infection rather than a viral one. Severe hyperemia of the pharyngeal mucosa (Choice D) is a possible finding in pharyngitis but is not specific to viral pharyngitis.
