A nurse is preparing to administer the hepatitis B vaccine to a client. Which of the following techniques should the nurse use to locate the deltoid muscle?
Locate the middle third of the anterior thigh between the greater trochanter of the femur and the lateral femoral condyle.
Place one finger across the acromion process and measure 3 fingerbreadths below to the midpoint and center of the lateral aspect of the upper arm.
Find the center of the anterior aspect of the thigh.
Locate the center of the arm between the elbow and the shoulder.
The Correct Answer is B
B. This method is recommended because the deltoid muscle is a large, rounded, triangular muscle that covers the shoulder joint.
A. This description is for locating the vastus lateralis muscle, which is commonly used for intramuscular injections in infants and young children, not adults.
C. This technique is used for locating the rectus femoris muscle, another site for intramuscular injections in infants and young children, not adults.
D. This location is too low, which could miss the muscle tissue and reduce the effectiveness of the vaccine.

Correct Answer is B
Explanation
B. This range represents the normal serum magnesium level. It is important for maintaining neuromuscular function and other vital processes in the body.
A. This range is too low for normal serum magnesium levels. Magnesium levels below this range can indicate hypomagnesemia, which can lead to symptoms such as muscle cramps, tremors, and cardiac arrhythmias.
C. This range is too high for normal serum magnesium levels. Elevated magnesium levels (hypermagnesemia) can occur in conditions such as renal failure or excessive magnesium intake, leading to symptoms like weakness, decreased reflexes, and in severe cases, cardiac arrest.
D. While this range is broader and includes the correct normal range (1.3-2.1 mEq/L), it also includes values that are below and above normal. Values below 1.3 mEq/L can indicate hypomagnesemia, while values above 2.1 mEq/L can indicate hypermagnesemia.
Correct Answer is ["D","E"]
Explanation
D. Persistent headache can occur with elevated levels of gentamicin, as it may indicate neurotoxicity. Gentamicin can cause neurotoxic effects, including headaches, especially when levels are elevated.
E. Tinnitus (ringing in the ears) is a classic symptom of gentamicin toxicity. Elevated gentamicin levels can lead to ototoxicity, which manifests as tinnitus among other auditory symptoms.
A. Insomnia is not typically associated with elevated levels of gentamicin. Elevated gentamicin levels are not known to cause insomnia.
B. Constipation is not typically associated with elevated levels of gentamicin. Elevated gentamicin levels are not known to cause constipation.
