Nursing Elites

1. A nurse is instructing a patient on the order of sensations with the application of an ice water bath for a swollen right ankle. Which of the following is the correct order of sensations experienced with an ice water bath?

• A. cold, burning, aching, and numbness
• B. burning, aching, cold, and numbness
• C. aching, cold, burning, and numbness
• D. cold, aching, burning, and numbness

Correct answer: A

Rationale: The correct order of sensations experienced with an ice water bath is cold, burning, aching, and numbness, as stated by the acronym CBAN (cold, burn, ache, numbness). Option A is the correct sequence. Choice B is incorrect as it starts with burning, which typically follows the cold sensation. Choice C is incorrect as aching is usually felt after the burning sensation. Choice D is incorrect as aching usually occurs after the burning sensation.

2. When a person using over-the-counter nasal decongestant drops experiences unrelieved and worsening nasal congestion, what should be instructed?

• A. switch to a stronger dose of the same medication.
• B. discontinue the medication for a few weeks.
• C. continue taking the same medication, but use it more frequently.
• D. use a combination of medications for better relief.

Correct answer: B

Rationale: When a person using over-the-counter nasal decongestant drops experiences unrelieved and worsening nasal congestion, it is crucial to discontinue the medication for a few weeks. Prolonged use of decongestant drops can lead to rebound congestion, which is relieved by stopping the medication for a period of time. Nasal congestion occurs due to various factors like infection, inflammation, or allergy, leading to swelling of the nasal cavity. Nasal decongestants work by stimulating alpha-adrenergic receptors, causing vasoconstriction and shrinking of nasal mucous membranes. However, prolonged use can result in vasodilation, worsening nasal congestion. Switching to a stronger dose of the same medication is not recommended as it can exacerbate the issue. Continuing the same medication more frequently or using a combination of medications are also not advised and may lead to side effects. Educating individuals on proper decongestant use and potential risks of prolonged usage is essential, especially for those with specific health conditions.

3. A physician orders a serum creatinine for a hospitalized client. The nurse should explain to the client and his family that this test:

• A. is normal if the level is 4.0 to 5.5 mg/dl.
• B. can be elevated with increased protein intake.
• C. is a better indicator of renal function than the BUN.
• D. reflects the fluid volume status of a person

Correct answer: C

Rationale: A serum creatinine level should be 0.7 to 1.5 mg/dl, and it does not vary with increased protein intake, so it is a better indicator of renal function than the BUN. Choice A is incorrect as a serum creatinine level of 4.0 to 5.5 mg/dl is not normal. Choice B is incorrect as serum creatinine is not affected by increased protein intake. Choice D is incorrect as serum creatinine primarily reflects renal function, not fluid volume status.

4. A client has been taking a drug (Drug A) that is highly metabolized by the cytochrome P-450 system. He has been on this medication for 6 months. At this time, he is started on a second medication (Drug B) that is an inducer of the cytochrome P-450 system. You should monitor this client for:

• A. increased therapeutic effects of Drug A.
• B. increased adverse effects of Drug B.
• C. decreased therapeutic effects of Drug A.
• D. decreased therapeutic effects of Drug B.

Correct answer: C

Rationale: When a client is taking a drug (Drug A) metabolized by the cytochrome P-450 system and is then started on another drug (Drug B) that induces this system, the metabolism of Drug A is increased. This results in decreased therapeutic effects of Drug A as it is broken down more rapidly. Monitoring is required to address potential reduced efficacy. The therapeutic effect of Drug A is diminished, not enhanced. Inducing the cytochrome P-450 system does not directly increase the adverse effects of Drug B. Although Drug B is an inducer, its therapeutic effects are not decreased as it is not metabolized faster.

5. A client is admitted to telemetry with a diagnosis of diabetes at 3pm. At 10pm, the client is unresponsive. BP is 98/64, Resp 38, HR 100, T 97. The nurse notes a fruity smell on the client's breath. The nurse recognizes that the client is in which acid-base imbalance?

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

Correct answer: C

Rationale: Based on the client's unresponsiveness, fruity breath smell, and the presence of diabetes, the nurse can infer that the client is experiencing diabetic ketoacidosis (DKA). DKA is a complication of diabetes characterized by the accumulation of ketones in the body, leading to metabolic acidosis. The fruity breath smell is due to the presence of ketones. Therefore, the correct acid-base imbalance in this scenario is metabolic acidosis. Choice A, respiratory acidosis, is incorrect because the scenario does not provide evidence of primary respiratory dysfunction. Choice B, respiratory alkalosis, is incorrect as the client's condition does not align with the typical causes and symptoms of respiratory alkalosis. Choice D, metabolic alkalosis, is incorrect as the symptoms and history provided do not suggest a state of metabolic alkalosis.
