For each assessment finding, click to indicate whether the findings from the client's assessment are generally associated with rotator cuff injury and/or humeral fracture. Each column must have at least one response selected.
1+ strength in left upper extremity
Decreased range of motion
Coolness of skin
Reduced pulse distal to injury
Pain with movement
The Correct Answer is {"A":{"answers":"A"},"B":{"answers":"A,B"},"C":{"answers":"A"},"D":{"answers":"A"},"E":{"answers":"A,B"}}
Rationale:
- 1+ strength in left upper extremity: Reduced strength in the affected arm could indicate a humeral fracture, which can impair muscle function and strength. A rotator cuff injury could cause pain, but it doesn’t necessarily lead to a reduction in strength to the extent seen with a humeral fracture.
- Decreased range of motion: Decreased range of motion is common with humeral fractures as the bone is likely immobilized and painful to move. A rotator cuff injury can also lead to decreased range of motion due to pain and limited ability to lift or rotate the arm.
- Coolness of skin: Coolness to the skin could indicate poor circulation, which can occur if there is vascular injury related to a humeral fracture or if there is significant swelling causing compression of blood vessels.Coolness is less commonly associated with rotator cuff injuries unless there is concurrent trauma affecting blood flow.
- Reduced pulse distal to injury: Reduced pulses can suggest vascular injury, which is more likely with a humeral fracture, especially if the bone fragments are displacing or compressing blood vessels.This is unlikely with a rotator cuff injury, as it primarily affects the tendons and muscles without significant impact on vascular structures.
- Pain with movement: Pain with movement is a classic symptom of a fracture, particularly when moving the arm or shoulder area. Pain with movement is also a hallmark of a rotator cuff injury, especially when the arm is raised or rotated.

Correct Answer is C
Explanation
A. Emollient: Emollient (stool softener) laxatives like docusate sodium help moisten stool but do not significantly increase stool volume or stimulate bowel movement. They are gentle but typically insufficient for long-term, low-frequency constipation.
B. Osmotic: Osmotic laxatives draw water into the bowel to promote peristalsis. They are effective but may cause electrolyte imbalances if used chronically. These are often reserved for when bulk-forming agents are ineffective.
C. Bulk-forming: Bulk-forming laxatives such as psyllium are typically the first-line recommendation for chronic constipation. They mimic dietary fiber by absorbing water, increasing stool bulk, and promoting regular bowel movements with minimal side effects.
D. Stimulant: Stimulant laxatives like senna or bisacodyl are stronger agents that promote bowel motility but can cause dependency if used long-term. They are not recommended as first-line therapy for chronic constipation related to diet.
Correct Answer is C
Explanation
A. Electromyography: Electromyography assesses electrical activity in muscles and is used to diagnose neuromuscular disorders. It is not relevant to evaluating bleeding tendencies or pinpoint skin spots, which suggest a hematologic issue like thrombocytopenia.
B. Skin biopsy: A skin biopsy might help diagnose dermatologic conditions, but it is invasive and not the initial step when systemic drug side effects like petechiae are suspected. The presence of red spots suggests a possible blood disorder requiring laboratory confirmation first.
C. Complete blood count: A CBC is essential to evaluate for thrombocytopenia, a known adverse effect of zidovudine. Pinpoint red spots, or petechiae, are often linked to low platelet counts, which require prompt detection and management to prevent serious complications.
D. Allergy test: Allergy testing identifies hypersensitivity reactions, typically associated with rashes or itching. Petechiae are not commonly caused by allergic reactions but are more indicative of blood abnormalities, making this test less immediately relevant.
