Nursing Elites

1. A client goes to the Emergency Department with acute respiratory distress and the following arterial blood gases (ABGs): pH 7.35, PCO2 40 mmHg, PO2 63 mmHg, HCO3 23, and oxygenation saturation (SaO2) 93%. Which of the following represents the best analysis of the etiology of these ABGs?

• A. tuberculosis (TB)
• B. pneumonia
• C. pleural effusion
• D. hypoxia

Correct answer: D

Rationale: A combined low PO2 and low SaO2 indicate hypoxia. The pH, PCO2, and HCO3 are normal. ABGs are not necessarily altered in TB or pleural effusion. In pneumonia, the PO2 and PCO2 might be low due to hypoxia stimulating hyperventilation, but the given ABG values specifically point to hypoxia as the primary issue.

2. What is the next step for a 64-year-old male diagnosed with COPD and CHF who shows a 10 lbs increase in total body weight over the last few days?

• A. Contact the patient's physician immediately.
• B. Check the intake and output on the patient's flow sheet.
• C. Encourage the patient to ambulate to reduce lower extremity edema.
• D. Check the patient's vitals every 2 hours.

Correct answer: B

Rationale: In a patient with COPD and CHF experiencing a sudden increase in total body weight, the priority is to check the intake and output on the patient's flow sheet to evaluate fluid balance. This assessment helps determine if the weight gain is due to fluid retention, which can exacerbate CHF. Contacting the physician may be necessary based on the intake and output findings. While encouraging ambulation is beneficial for circulation, it may not address the root cause of fluid retention. Checking vitals every 2 hours is important for monitoring stability but may not pinpoint the reason behind the weight gain.

3. 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.

4. A patient has recently been prescribed Lidocaine Hydrochloride. Which of the following symptoms may occur with an overdose?

• A. Memory loss and lack of appetite
• B. Confusion and fatigue
• C. Heightened reflexes
• D. Tinnitus and spasticity

Correct answer: B

Rationale: The correct answer is 'Confusion and fatigue.' Lidocaine Hydrochloride, when taken in excess, can lead to symptoms such as confusion and fatigue. It affects the central nervous system, leading to these cognitive and physical impairments. Choice A ('Memory loss and lack of appetite') is incorrect because memory loss is not a common symptom of Lidocaine Hydrochloride overdose, and lack of appetite is not a typical effect. Choice C ('Heightened reflexes') is incorrect as Lidocaine Hydrochloride overdose usually depresses reflexes rather than heightening them. Choice D ('Tinnitus and spasticity') is incorrect as tinnitus and spasticity are not commonly associated with Lidocaine Hydrochloride overdose.

5. Which sexually transmitted disease, sometimes referred to as the silent STD, is more common than gonorrhea and a leading cause of PID?

• A. Genital herpes.
• B. Trichomoniasis.
• C. Syphilis.
• D. Chlamydia.

Correct answer: D

Rationale: The correct answer is Chlamydia. Chlamydia is a common sexually transmitted infection that can often be asymptomatic, earning it the nickname 'silent STD.' It is more common than gonorrhea and is a leading cause of Pelvic Inflammatory Disease (PID). Genital herpes (Choice A) is a viral infection, not a bacterial STD like chlamydia. Trichomoniasis (Choice B) is a parasitic infection and not commonly associated with causing PID. Syphilis (Choice C) is a bacterial infection but is not as common as chlamydia and is not a leading cause of PID.
