A nurse is preparing to administer penicillin IM to an adult client. Which of the following angles should the nurse use for injection into the client's ventrogluteal muscle?

60°

45°

75°

90°

Answer and Explanation

The Correct Answer is D

D. A 90° angle (perpendicular to the skin surface) is typically used for IM injections into muscles where the needle needs to penetrate deeply into the muscle tissue.

A. 60° angle is commonly used for IM injections in the deltoid muscle or thigh. However, it may not be optimal for the ventrogluteal site, which typically requires a different approach due to its deeper location and muscle structure.

B. A 45° angle is typically used for subcutaneous injections, where the needle is inserted into the fatty layer just below the skin surface.

C. This angle is steeper than 60° and is sometimes used for IM injections into muscles with thicker tissue or larger muscle mass.

Correct Answer is D

Explanation

D. Muscle weakness is a hallmark sign of hypokalemia. Potassium is crucial for proper muscle contraction, and low levels can impair muscle function. This weakness can affect skeletal muscles (resulting in fatigue, cramps, or generalized weakness) as well as smooth muscles (contributing to constipation or other gastrointestinal symptoms).

A. Hypokalemia is not typically associated with hyperactive bowel sounds.

B. Cerebral edema is not typically associated with hypokalemia. Instead, cerebral edema can occur with conditions such as hyponatremia (low sodium levels) or other metabolic disturbances.

C. Hypokalemia is more commonly associated with hypotension (low blood pressure) rather than hypertension. Low potassium levels can affect vascular smooth muscle tone, potentially leading to vasodilation and hypotension.

A. Dispose of used razors in wastebaskets. B. Replace sharps containers when they are full. C. Use two hands to recap a needle after administering a medication. D. Break needles on syringes before disposal.

Correct Answer is B

Explanation

B. Sharps containers should be replaced when they are 3/4 full to prevent overfilling, which could increase the risk of needlesticks when trying to dispose of sharps. Ensuring sharps containers are not overfilled helps maintain a safe environment by reducing the risk of accidental puncture injuries during disposal.

A. Used razors should be disposed of in puncture-resistant sharps containers, not in regular wastebaskets. Sharps containers are specifically designed to safely contain sharp objects to prevent accidental injuries.

C. Using two hands to recap a needle is unsafe and increases the risk of accidental needlestick injuries. It's important to educate healthcare workers to avoid recapping needles whenever possible.

D. Breaking needles before disposal is unsafe and increases the risk of injury. Needles should be disposed of intact in a puncture-resistant sharps container.
