A nurse is caring for a client who has hyperemesis gravidarum.
Which of the following laboratory tests should the nurse anticipate?

Choice A rationale

The ventrogluteal muscle, located in the hip, is a safe site for intramuscular injections in adults and children older than seven months due to its distance from major nerves and blood vessels. However, the vastus lateralis muscle in the thigh is the preferred site for IM injections in newborns and infants due to its well-developed muscle mass and accessibility.

Choice B rationale

The deltoid muscle, located in the upper arm, is small and not well-developed in newborns, making it an unsuitable site for intramuscular injections. There is also a risk of injury to the brachial nerve and blood vessels in this area in neonates.

Choice C rationale

The dorsogluteal muscle, located in the buttocks, is no longer the recommended site for intramuscular injections in infants and young children due to the proximity of the sciatic nerve and major blood vessels, increasing the risk of nerve damage.

Choice D rationale

The vastus lateralis muscle, located on the anterolateral aspect of the thigh, is the recommended site for intramuscular injections in newborns. It is a large, well-developed muscle that is easily accessible and away from major nerves and blood vessels, making it a safe and effective site for administering vitamin K to prevent hemorrhagic disease of the newborn.

Step 1: Heart rate of 110/min scores 2 points (normal heart rate >100).

Step 2: Slow weak cry scores 1 point (good strong cry scores 2, no cry scores 0).

Step 3: Some flexion of extremities scores 1 point (active movement scores 2, limp scores 0).

Step 4: Grimace in response to suctioning scores 1 point (coughing or sneezing scores 2, no response scores 0).

Step 5: Body pink, blue extremities scores 1 point (completely pink scores 2, completely blue or pale scores 0).

Step 6: Total Apgar score is the sum of the scores from each category: 2 + 1 + 1 + 1 + 2 = 7. Final calculated answer: 7.
