Nursing Elites

1. Which of the following conditions may cause an increased respiratory rate?

• A. Stooped posture
• B. Narcotic analgesics
• C. Injury to the brain stem
• D. Anemia

Correct answer: D

Rationale: Anemia can lead to an increased respiratory rate. In anemia, there are decreased levels of hemoglobin in red blood cells, which are responsible for carrying oxygen to the body's tissues. To compensate for the reduced oxygen-carrying capacity, the body increases the respiratory rate to bring in more oxygen. Stooped posture (Choice A) is not directly related to an increased respiratory rate. Narcotic analgesics (Choice B) are more likely to cause a decreased respiratory rate due to their central nervous system depressant effects. Injury to the brain stem (Choice C) can affect respiratory function but may not necessarily lead to an increased respiratory rate.

2. As a nursing supervisor in a long-term care facility, you prioritize strict infection control prevention measures due to the understanding that the normal aging process weakens the body's defenses. Which theory of aging supports the necessity of strict infection control prevention measures?

• A. The Programmed Longevity Theory
• B. The Immunological Theory of Aging
• C. The Endocrine Theory
• D. The Rate of Living Theory

Correct answer: B

Rationale: The theory of aging that aligns with the need for strict infection control prevention measures is the Immunological Theory of Aging. This theory posits that aging leads to a decline in the body's immune defenses and a reduced ability of antibodies to protect against infections. The other theories do not directly address the impact of aging on the immune system. The Programmed Longevity Theory focuses on genetic changes affecting aging, the Endocrine Theory emphasizes hormonal changes, and the Rate of Living Theory relates longevity to the rate of oxygen metabolism.

3. Mr. N is a client who entered the hospital with a diagnosis of diabetic ketoacidosis. The nurse enters his room to check his vital signs and finds him breathing at a rate of 32 times per minute; his respirations are deep and regular. Which type of respiratory pattern is Mr. N most likely exhibiting?

• A. Kussmaul respirations
• B. Cheyne-Stokes respirations
• C. Biot's respirations
• D. Cluster breathing

Correct answer: A

Rationale: Mr. N is most likely exhibiting Kussmaul respirations. Kussmaul respirations are a form of hyperventilation associated with conditions like metabolic acidosis. They are characterized by rapid, regular, and deep breathing. This type of respiratory pattern helps the body compensate for metabolic acidosis by attempting to blow off excess carbon dioxide. This pattern is different from Cheyne-Stokes respirations (choice B), which are characterized by alternating periods of deep, rapid breathing followed by apnea. Biot's respirations (choice C) are characterized by groups of quick, shallow inspirations followed by irregular periods of apnea, and Cluster breathing (choice D) involves clusters of breaths followed by periods of apnea, often seen in patients with brain injury or neurological conditions.

4. A nurse is performing an end-of-shift count of narcotics kept in the locked cabinet. The narcotic log states there should be 26 oxycodone pills left, but there are only 24 in the drawer. What is the first action of the nurse?

• A. Perform the count again
• B. Contact the pharmacy to determine if the narcotic log is incorrect
• C. Check with the last nurse to sign out narcotics from the system
• D. Notify the house supervisor that narcotic medications are missing

Correct answer: A

Rationale: The first action the nurse should take in this situation is to perform the count again. This step is crucial to ensure there was no miscount during the initial check. By verifying the count, the nurse can confirm if there is indeed a discrepancy in the number of oxycodone pills. Contacting the pharmacy, checking with the last nurse, or notifying the house supervisor should only be considered after ensuring the count is accurate. It's important to rule out any human error before escalating the issue to others.

5. A healthcare professional is preparing to draw a blood specimen from an adult client's central line. All of the following actions for this procedure are correct EXCEPT:

• A. Disconnect the current infusion
• B. Clean the cap with alcohol and attach a 5 cc syringe
• C. Draw 5 cc of a blood sample to discard
• D. Flush with saline after the sample

Correct answer: B

Rationale: When drawing a blood specimen from a central line, the healthcare professional should disconnect any infusions that are currently running and that could contaminate the specimen. It is important to use a minimum size of a 10 cc syringe when using a central line to avoid placing too much pressure on the catheter. Cleaning the cap with alcohol and attaching a 5 cc syringe is not appropriate as a larger syringe size should be used for this procedure. Drawing 5 cc of a blood sample to discard and flushing with saline after the sample are correct steps in the process of drawing a blood specimen from a central line.
