What describes a gene when the same allele is inherited from both parents?
Heterozygous
Recessive
Dominant
Monozygous
The Correct Answer is D
A. Heterozygous refers to having two different alleles for a gene, one inherited from each parent.
B. Recessive refers to an allele that only expresses its trait if two copies are present (homozygous), but this term does not describe the inheritance pattern itself.
C. Dominant refers to an allele that expresses its trait even if only one copy is present, but again, this term does not describe the inheritance pattern.
D. Homozygous describes a gene when the same allele is inherited from both parents (e.g., AA or aa).

Explanation
A. Presence of fat embolisms: Fat embolisms can occur after fractures, particularly of long bones, and must be considered as they can lead to serious complications such as respiratory distress.
B. Pulse strength (0/4 to 4/4): Assessing pulse strength is crucial in musculoskeletal trauma to evaluate circulation and ensure there is no compromise to blood flow to the affected limb.
C. Age: While age can influence the healing process and susceptibility to injury, it is not a direct indicator of musculoskeletal trauma severity.
D. Circulation (capillary refill less than three seconds): Capillary refill time is a key assessment to evaluate circulation and the potential impact of musculoskeletal trauma on blood flow.
E. Potassium levels: Potassium levels are not directly related to musculoskeletal trauma assessment.
F. Level of vitamin D: Vitamin D levels do not provide immediate information relevant to acute musculoskeletal trauma.

Explanation
A. Bladder cancer: The presence of malignant epithelial cells in the urinalysis and the scheduled transurethral resection are indicative of bladder cancer. Bladder cancer often presents with symptoms such as urinary retention, nocturia, and chronic cystitis, especially in older adults and those with risk factors like nicotine dependence.
B. Bladder adenoma: This is less common and typically benign, not associated with malignant epithelial cells.
C. Renal cell carcinoma: This affects the kidneys, not the bladder.
D. Renal epithelial cell cancer: This term is less specific and typically refers to cancers of the renal parenchyma, not the bladder.
