Nursing Elites

1. Which hormone is made in the pituitary gland and increases water absorption in the kidney?

• A. Intracellular fluid
• B. Interstitial fluid
• C. Plasma
• D. ADH

Correct answer: D

Rationale: The correct answer is D, ADH (Antidiuretic hormone). ADH is produced by the pituitary gland and functions to increase water reabsorption in the kidneys. Choices A, B, and C are incorrect as they do not refer to a hormone responsible for increasing water absorption in the kidney.

2. A nurse evaluates the following arterial blood gas values in a client: pH 7.48, PaO2 98 mm Hg, PaCO2 28 mm Hg, and HCO3 22 mEq/L. Which client condition should the nurse correlate with these results?

• A. Diarrhea and vomiting for 36 hours
• B. . Anxiety-induced hyperventilation
• C. Chronic obstructive pulmonary disease (COPD)
• D. Diabetic ketoacidosis and emphysema

Correct answer: B

Rationale:

3. A nurse is caring for an older adult client who is admitted with moderate dehydration. Which intervention should the nurse implement to prevent injury while in the hospital?

• A. Ask family members to speak quietly to keep the client calm.
• B. Assess urine color, amount, and specific gravity each day.
• C. Encourage the client to drink at least 1 liter of fluids each shift.
• D. Dangle the client on the bedside before ambulating.

Correct answer: D

Rationale: The correct answer is to 'dangle the client on the bedside before ambulating.' This intervention helps prevent orthostatic hypotension, a drop in blood pressure when changing positions, which is crucial in preventing falls and related injuries in older adult clients. Asking family members to speak quietly (Choice A) may help keep the client calm but does not directly address the risk of injury. Assessing urine parameters (Choice B) is important for monitoring hydration status but does not specifically prevent injury. Encouraging increased fluid intake (Choice C) is essential for managing dehydration but does not directly address the risk of injury during ambulation.

4. Which electrolyte is important in the formation of the thyroid hormones?

• A. Sodium
• B. Iodine
• C. Iron
• D. Chloride

Correct answer: B

Rationale: Iodine is the correct answer because it is essential for the synthesis of thyroid hormones. The thyroid gland incorporates iodine into thyroid hormones such as thyroxine (T4) and triiodothyronine (T3). These hormones are crucial for regulating metabolism, growth, and development. Sodium, iron, and chloride are not directly involved in the formation of thyroid hormones, making them incorrect choices.

5. When preparing a site for the insertion of an IV catheter, how should excess hair at the site be treated?

• A. Leaving the hair intact
• B. Shaving the area
• C. Clipping the hair in the area
• D. Removing the hair with a depilatory

Correct answer: C

Rationale: The correct answer is to clip the hair in the area. Excess hair at the site of IV catheter insertion should be removed because it can be a potential source of infection. Clipping the hair is preferred over shaving because shaving can cause skin abrasions, increasing the risk of infection. Using depilatories is not recommended as they can irritate the skin, which is undesirable when preparing a clean site for an invasive procedure. Therefore, clipping the hair in the area is the most appropriate and safe method to prepare the site for IV catheter insertion.
