1. A healthcare provider is reviewing the laboratory report of a client who has been taking lithium carbonate for the past 12 months. The provider notes a lithium level of 0.8 mEq/L. Which of the following orders from the provider should the healthcare provider expect?

A. Withhold the next dose
B. Increase the dosage
C. Discontinue the medication
D. Administer the medication

Correct answer: D

Rationale: A lithium level of 0.8 mEq/L falls within the therapeutic range for maintaining the drug's effectiveness while minimizing toxicity. Therefore, the appropriate action would be to continue administering the medication as prescribed by the healthcare provider to maintain the therapeutic effect for the client.

2. What is the appropriate needle gauge for intradermal injection?

A. 20G
B. 22G
C. 25G
D. 26G

Correct answer: D

Rationale: Intradermal injections require a very fine needle to be used to deliver the medication into the dermis layer of the skin. A 26G needle is typically used for intradermal injections as it is thin enough to penetrate the skin's surface and deposit the medication accurately.

3. In which of the following organs does the exchange of gases take place?

A. Kidneys
B. Lungs
C. Liver
D. Heart

Correct answer: B

Rationale: The exchange of gases, specifically oxygen and carbon dioxide, occurs in the lungs. In the lungs, oxygen from the air we breathe enters the bloodstream, while carbon dioxide is removed from the bloodstream and exhaled. This process is essential for respiration and supplying the body with oxygen for energy production. The kidneys filter waste from the blood to produce urine and regulate fluid balance (Choice A). The liver is involved in detoxification, protein synthesis, and producing bile (Choice C). The heart is responsible for pumping blood throughout the body to deliver oxygen and nutrients (Choice D).

4. To assess the kidney function of a patient with an indwelling urinary (Foley) catheter, the nurse measures the hourly urine output. When should she notify the physician?

A. Less than 30 ml/hour
B. 64 ml in 2 hours
C. 90 ml in 3 hours
D. 125 ml in 4 hours

Correct answer: A

Rationale: Notifying the physician is necessary when the urine output is less than 30 ml/hour as it indicates impaired kidney function. Adequate urine output is essential for monitoring kidney function, and a urine output less than 30 ml/hour could suggest potential renal issues that require medical attention.

5. What is the abbreviation for micro drop?

A. Âµgtt
B. gtt
C. mdr
D. mgts

Correct answer: A

Rationale: The correct abbreviation for micro drop is 'Âµgtt,' where the symbol 'Âµ' represents micro and 'gtt' stands for drop. Choice B, 'gtt,' is the abbreviation for drop, not specifically for micro drop. Choice C, 'mdr,' and Choice D, 'mgts,' are not standard abbreviations for micro drop and are incorrect.
