1. When choosing a needle gauge for an intramuscular injection in a 12-year-old boy, which of the following gauges would you choose?

• A. 27 gauge
• B. 25 gauge
• C. 22 gauge
• D. 20 gauge

Correct answer: C

Rationale: The correct answer is 22 gauge. A 22-gauge needle is recommended for school-age children, toddlers, and adolescents due to their muscle mass and tolerance. In infants, a smaller gauge (23-25) is preferred as their muscles are less developed and more sensitive. Choice A, 27 gauge, is too thin for an intramuscular injection in a 12-year-old boy. Choice B, 25 gauge, is more suitable for infants than for a 12-year-old. Choice D, 20 gauge, is too thick and not typically used for intramuscular injections in children.

2. A client has been receiving cyanocobalamin (B12) injections for the past 6 weeks. Which laboratory finding indicates that the medication is having the desired effect?

• A. Neutrophil count of 60%
• B. Basophil count of 0.5%
• C. Monocyte count of 2%
• D. Reticulocyte count of 1%

Correct answer: D

Rationale: Cyanocobalamin is a B12 medication used for pernicious anemia. A reticulocyte count of 1% indicates the desired effect of the medication, as reticulocytes are immature red blood cells that increase in response to B12 therapy, improving anemia. Neutrophils, basophils, and monocytes are white blood cells and are not directly influenced by B12 injections, making them incorrect choices.

3. A nurse is caring for a client with an elevated cortisol level. The nurse can expect the client to exhibit symptoms of:

• A. urinary excess
• B. hyperpituitarism
• C. urinary deficit
• D. hyperthyroidism

Correct answer: C

Rationale: Elevated cortisol levels can lead to sodium and fluid retention and potassium deficit, resulting in urinary deficit. This imbalance in electrolytes and fluid can cause a decrease in urinary output. Choices B, hyperpituitarism, and D, hyperthyroidism, are incorrect as they do not directly relate to the symptoms expected with elevated cortisol levels. Option A, urinary excess, is also incorrect as high cortisol levels typically lead to fluid retention and urinary deficit, not excess.

4. Which type of exercises might be prescribed to strengthen the pelvic floor muscles of a client with urinary incontinence?

• A. Kegel
• B. resistance
• C. passive
• D. stretching

Correct answer: A

Rationale: The correct answer is Kegel. Kegel exercises are specifically designed to strengthen the pelvic floor muscles, making them an effective treatment for urinary incontinence. These exercises involve contracting and relaxing the pelvic floor muscles, which helps to improve muscle tone and control. Choice B, resistance exercises, may not directly target the pelvic floor muscles as effectively as Kegel exercises. Passive exercises (Choice C) do not actively engage the muscles and are unlikely to strengthen the pelvic floor. Stretching exercises (Choice D) focus on increasing flexibility rather than muscle strength, so they are not the most appropriate for strengthening the pelvic floor muscles in the context of urinary incontinence.

5. What are the major electrolytes in the extracellular fluid?

• A. potassium and chloride
• B. potassium and phosphate
• C. sodium and chloride
• D. sodium and phosphate

Correct answer: C

Rationale: The correct answer is sodium and chloride. These two electrolytes are the major components of extracellular fluid. Potassium and phosphate (Choice B) are not the major electrolytes in the extracellular fluid. Potassium is primarily an intracellular ion, and phosphate is more abundant in the intracellular fluid and bones. Sodium and phosphate (Choice D) are also not the major electrolytes in the extracellular fluid. Chloride plays a crucial role in maintaining electrolyte balance and is predominantly found in extracellular fluid alongside sodium.
