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. Erythropoietin used to treat anemia in clients with renal failure should be given in conjunction with:

• A. iron, folic acid, and B12.
• B. an increase in protein in the diet.
• C. vitamins A and C.
• D. an increase in calcium in the diet.

Correct answer: A

Rationale: Erythropoietin is necessary for red blood cell (RBC) production, and in clients with renal failure who lack endogenous erythropoietin, exogenous erythropoietin is administered. However, for erythropoietin to effectively stimulate RBC production, adequate levels of iron, folic acid, and vitamin B12 are crucial. These nutrients are essential for RBC synthesis and maturation. Therefore, the correct answer is to give iron, folic acid, and B12 with erythropoietin. Choice B, an increase in protein in the diet, is not necessary for RBC production and may exacerbate uremia in clients with renal failure. Choices C and D, vitamins A and C, and an increase in calcium in the diet, respectively, are not directly related to RBC production and are not required to enhance the effectiveness of erythropoietin.

3. Which of the following is likely to increase the risk of sexually transmitted disease?

• A. alcohol use
• B. certain types of sexual practices
• C. oral contraception use
• D. all of the above

Correct answer: D

Rationale: All of the above factors are likely to increase the risk of sexually transmitted diseases (STDs). Alcohol use can impair judgment, leading to risky sexual behavior. Certain types of sexual practices, especially unprotected sex or multiple partners, increase the likelihood of contracting STDs. While oral contraception use does not directly increase the risk of STDs, it does not protect against them either. Therefore, all the choices (alcohol use, certain types of sexual practices, and oral contraception use) can contribute to an increased risk of contracting STDs.

4. Teaching the client with gonorrhea how to prevent reinfection and further spread is an example of

• A. primary prevention
• B. secondary prevention
• C. tertiary prevention
• D. primary health care prevention

Correct answer: B

Rationale: The correct answer is B: secondary prevention. This type of prevention focuses on reducing the impact of a disease by early detection and treatment. In the case of gonorrhea, teaching the client how to prevent reinfection and further spread falls under secondary prevention because it aims to reduce the prevalence and morbidity of the disease. Choice A (primary prevention) involves measures to prevent the disease from occurring in the first place, such as vaccination. Choice C (tertiary prevention) focuses on managing the long-term consequences of a disease to prevent complications. Choice D (primary health care prevention) is not a recognized term in prevention strategies.

5. The physician wants to know if a client is tolerating their total parenteral nutrition. Which of the following laboratory tests is likely to be ordered?

• A. triglyceride level
• B. liver function tests
• C. a glucose tolerance test
• D. a complete blood count

Correct answer: B

Rationale: The liver is crucial in processing nutrients and medications received through total parenteral nutrition. Liver function tests assess various enzymes produced by the liver, including prothrombin time/partial prothrombin time, serum glutamic oxaloacetic and pyruvic transaminases, gamma glutamyl transpeptidase, albumin, and alkaline phosphatase. Monitoring these enzymes can help determine if the liver is functioning properly to metabolize the nutrients from TPN. Triglyceride levels (Choice A) primarily evaluate the body's ability to clear fats, not specifically related to TPN tolerance. A glucose tolerance test (Choice C) is used to diagnose diabetes by measuring blood glucose levels after ingesting a glucose-rich solution, not directly related to TPN tolerance. A complete blood count (Choice D) assesses blood components such as red blood cells, white blood cells, and platelets but does not provide specific information about TPN tolerance.
