Nursing Elites

1. A 50-milliliter (ml) bolus of normal saline fluid is ordered by the physician. The physician wants it to infuse in 30 minutes. The nurse should set the pump rate at:

• A. 100 ml per hour for one hour.
• B. 60 ml per hour for one-half hour
• C. 120 ml per hour for one hour.
• D. 50 ml per hour for one hour.

Correct answer: A

Rationale: To infuse a 50 ml bolus in 30 minutes, the rate should be calculated as follows: 50 ml / 30 min = 100 ml per hour. Therefore, the correct answer is to set the pump rate at 100 ml per hour for one hour. Choice A is the correct rate based on the calculation. Choices B, C, and D all provide incorrect rates that do not match the physician's order. Choice B would only deliver 30 ml in 30 minutes, not the ordered 50 ml. Choice C would deliver 120 ml in one hour, which is 20 ml more than ordered. Choice D would only provide 25 ml over 30 minutes, not the full 50 ml prescribed.

2. The client is admitted with chronic obstructive pulmonary disease. Blood gases reveal pH 7.36, CO2 45, O2 84, HCO3 28. The nurse would assess the client to be in:

• A. Uncompensated acidosis
• B. Compensated alkalosis
• C. Compensated respiratory acidosis
• D. Uncompensated metabolic acidosis

Correct answer: C

Rationale: The client is experiencing compensated respiratory acidosis. The pH is within the normal range but is lower than 7.40, indicating acidity. The elevated CO2 level and low O2 level suggest respiratory involvement. The slightly elevated HCO3 level indicates a compensatory mechanism. In respiratory acidosis, the pH will be inversely related to the CO2 and bicarb levels, with elevated CO2 and HCO3 levels contributing to acidosis. Choices A, B, and D are incorrect because they do not align with the presented blood gas values and the compensatory response observed in this case.

3. How can medication bound to protein affect drug availability?

• A. enhanced drug availability
• B. rapid distribution of the drug to receptor sites
• C. less availability to produce desired medicinal effects
• D. increased metabolism of the drug by the liver

Correct answer: C

Rationale: Medication bound to protein reduces the availability of the drug to produce desired medicinal effects because only unbound drugs can effectively bind to active receptor sites. When a drug is bound to protein, it cannot bind with receptor sites, limiting its therapeutic impact. Choice A is incorrect because drug availability is reduced when it is bound to protein. Choice B is incorrect as rapid distribution to receptor sites is not possible if the drug is bound to protein and cannot bind with receptors. Choice D is incorrect as metabolism does not increase when the drug is bound to protein; the liver first needs to separate the drug from the protein before metabolism can occur.

4. A client is admitted with a diagnosis of Multiple Drug Use. The nurse should plan care based on knowledge that

• A. Multiple drug use is common.
• B. People might use more than one drug to enhance the effect or relieve withdrawal symptoms.
• C. Combining alcohol and barbiturates can be dangerous due to their combined depressant effects.
• D. Assessment and intervention are more complex with multiple drug use due to the synergistic effects.

Correct answer: B

Rationale: When caring for a client with Multiple Drug Use, it is important to understand that individuals may use more than one drug simultaneously or sequentially to enhance the effect of a particular drug or to relieve withdrawal symptoms. This practice is common among substance users. For example, heroin users may also consume alcohol, marijuana, or benzodiazepines. Combining drugs can have various effects, such as intensifying intoxication or alleviating withdrawal symptoms. It is crucial to recognize that multiple drug use can complicate assessment and intervention due to the diverse effects of different substances on the client's health. Option A is incorrect as multiple drug use is indeed common, not uncommon. Option C is incorrect because combining alcohol and barbiturates can be dangerous due to their combined depressant effects. Option D is incorrect because multiple drug use complicates assessment and intervention rather than making them easier, as the effects of different drugs on the client need to be carefully considered.

5. When assessing a client with glaucoma, a nurse expects which of the following findings?

• A. Complaints of double vision
• B. Complaints of halos around lights
• C. Intraocular pressure of 15 mm Hg
• D. Soft globe on palpation

Correct answer: B

Rationale: When assessing a client with glaucoma, a common finding is complaints of halos around lights. Other symptoms of glaucoma include loss of peripheral vision or blind spots, reddened sclera, firm globe, decreased accommodation, and occasional eye pain. Glaucoma may be asymptomatic until permanent damage to the optic nerve and retina occurs. Double vision is not a typical symptom of glaucoma. In terms of intraocular pressure, normal levels range from 10 to 21 mm Hg, making an intraocular pressure of 15 mm Hg within the normal range. A soft globe on palpation is not a typical finding in glaucoma.
