Correct Answer: A

Rationale: The clinical presentation of urinary urgency, frequency, and nocturia along with prostate enlargement with a smooth, firm consistency on digital rectal examination (DRE) is classic for benign prostatic hyperplasia (BPH). BPH is a common condition in aging men characterized by non-malignant growth of the prostate gland, which can cause varying degrees of lower urinary tract symptoms due to obstruction of the urethra. In contrast, prostate cancer typically presents with findings like an asymmetric, hard, or nodular prostate on DRE, while prostatitis presents with symptoms like fever, perineal pain, and systemic symptoms. Urinary tract infection (UTI) may present with dysuria, frequency, urgency, and suprapubic pain, but it does not usually cause prostate enlargement.

Correct Answer: A

Rationale: The clinical presentation of recurrent fever, sore throat, cervical lymphadenopathy, leukocytosis with atypical lymphocytes, and positive heterophile antibody test (Monospot test) is highly indicative of infectious mononucleosis caused by the Epstein-Barr virus (EBV). EBV is a member of the herpesvirus family and is a common cause of infectious mononucleosis. The atypical lymphocytes seen on peripheral blood smear are reactive T lymphocytes responding to the EBV infection. The Monospot test detects heterophile antibodies produced in response to EBV infection.

Correct Answer: C

Rationale: Clients undergoing nasogastric suctioning are at highest risk for developing metabolic imbalances, specifically metabolic acidosis. Nasogastric suctioning can lead to the loss of gastric acid, which in turn can cause metabolic acidosis due to a decrease in bicarbonate levels in the body. This disruption in the acid-base balance can result in symptoms such as confusion, headache, and overall malaise. It is crucial for the nurse to monitor the client's acid-base status closely and provide appropriate interventions to prevent or correct metabolic acidosis.

Correct Answer: D

Rationale: It is NOT recommended to use the same syringe and needle in administering two different vaccines. This is to prevent contamination or mixing of different vaccines, which could potentially affect their effectiveness or pose a risk to the individual receiving the vaccines. It is important to use separate syringes and needles for each vaccine to ensure proper administration and prevent any adverse reactions.

Correct Answer: B

Rationale: The term "collaborative" best fits the situation where a member of the Research Committee wishes to conduct a study involving an interdisciplinary team of colleagues. Collaboration refers to individuals, in this case, researchers or professionals from different disciplines coming together, sharing their expertise, and working collectively towards a common goal or project. In an interdisciplinary study, involving a collaborative approach enhances the diversity of perspectives, skills, and knowledge brought to the research, leading to more comprehensive and well-rounded outcomes. This type of study fosters cooperation, communication, and synergy among team members, thereby promoting innovation and understanding across different areas of expertise.
