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. During an assessment, a client with a long history of smoking and suspected laryngeal cancer will most likely report which early manifestation?

• A. Dysphagia
• B. Hoarseness
• C. Dyspnea
• D. Weight loss

Correct answer: B

Rationale: In clients with laryngeal cancer, hoarseness is often one of the earliest manifestations due to vocal cord involvement. The irritation and inflammation caused by the tumor affect the vocal cords, leading to changes in voice quality. Dysphagia (choice A) typically occurs later as the tumor grows and interferes with swallowing. Dyspnea (choice C) and weight loss (choice D) may occur as the cancer progresses, but hoarseness is usually among the first signs to manifest in laryngeal cancer.

3. 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• C. Outdated medications stored in the kitchen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.

4. Prior to a cardiac catheterization, what is the most important action for the nurse to take?

• A. Ensure that the client has been NPO for 6 hours before the procedure.
• B. Administer pre-procedure medications as ordered.
• C. Verify that informed consent has been obtained.
• D. Assess the client for any allergies, especially to iodine or shellfish.

Correct answer: D

Rationale: Assessing the client for allergies, particularly to iodine or shellfish, is crucial before a cardiac catheterization because the contrast dye used during the procedure can lead to allergic reactions. Identifying any allergies beforehand allows the healthcare team to take necessary precautions to prevent potential adverse reactions and ensure the client's safety.

5. A client is going to be admitted for a scheduled surgical procedure. Which action does the nurse explain is the most important thing the client can do to protect against errors?

• A. Bring a list of all medications and their purposes.
• B. Keep the doctor's phone number close by.
• C. Ensure all providers wash their hands before entering the room.
• D. Document the name of each caregiver who enters the room.

Correct answer: A

Rationale: The most important action a client can take to protect against errors is to bring a list of all medications and their purposes. This helps ensure that the healthcare team has accurate information about the client's medications, reducing the risk of medication errors, which are the most common type of healthcare mistake. Knowing the medications and their purposes can also aid in preventing drug interactions and adverse effects during the surgical procedure.
