The nurse is preparing to administer an intramuscular injection to an 8-month-old infant. Which site would the nurse select?
Rectus femoris
Vastus lateralis
Dorsogluteal muscle
Deltoid
The Correct Answer is B
A. Rectus femoris: Although accessible, the rectus femoris is not the preferred injection site in infants because it is close to major nerves and blood vessels, and injections here can cause discomfort and inconsistent absorption of medication.
B. Vastus lateralis: This is the safest and most recommended intramuscular injection site for infants under 12 months. It is a large, well-developed muscle located on the anterolateral thigh and free from major nerves or blood vessels, ensuring effective medication absorption and minimal risk of injury.
C. Dorsogluteal muscle: This site should not be used in infants due to the risk of sciatic nerve injury and underdeveloped gluteal muscles, which make proper absorption unreliable. It becomes safer only in older children and adults.
D. Deltoid: The deltoid muscle is too small in infants to safely accommodate an intramuscular injection and has limited muscle mass, increasing the risk of nerve damage. It is typically reserved for children over 18 months, particularly for small-volume vaccines.

Correct Answer is B
Explanation
A. Amenorrhea: Uterine fibroids are more commonly associated with menorrhagia (heavy bleeding) or metrorrhagia (irregular bleeding) rather than amenorrhea. Fibroids cause increased uterine lining surface area and vascular congestion, leading to excessive rather than absent menstrual flow.
B. Chronic pelvic pain: Chronic pelvic pain or a feeling of pelvic pressure is a classic symptom of uterine fibroids. The enlarging fibroids can compress surrounding structures, causing discomfort, lower abdominal fullness, and sometimes radiating pain to the lower back or thighs.
C. Upper back pain: Fibroids are located in the uterus, within the pelvic cavity, and are unlikely to cause upper back pain. Pain from fibroids typically presents in the lower abdomen or pelvis due to localized pressure.
D. Diarrhea: Gastrointestinal symptoms like diarrhea are not typically associated with fibroids. If present, bowel symptoms are more likely due to large fibroids exerting pressure on the rectum, leading to constipation rather than increased bowel motility.
Correct Answer is D
Explanation
A. Uterine fibroids: Fibroids are benign tumors of the uterine muscle that can cause heavy menstrual bleeding, pelvic pain, or pressure but do not usually cause a dragging sensation or the feeling of a lump within the vagina.
B. Endocervical polyps: Cervical polyps are small, benign growths on the cervix that may cause spotting or bleeding after intercourse but do not produce a sensation of pelvic heaviness or a vaginal lump.
C. Urinary incontinence: This condition involves involuntary leakage of urine, often due to weakened pelvic floor muscles, but it does not cause the sensation of a vaginal lump or dragging feeling.
D. Pelvic organ prolapse: Pelvic organ prolapse occurs when pelvic support structures weaken, allowing organs such as the uterus, bladder, or rectum to descend into the vaginal canal. The client’s description of a dragging sensation and feeling of a lump are classic symptoms.
