A patient presents with foul-smelling diarrhea containing cysts upon microscopic examination. Which of the following parasites is most likely responsible for this infection?
- A. Giardia lamblia
- B. Entamoeba histolytica
- C. Cryptosporidium parvum
- D. Cyclospora cayetanensis
Correct Answer: B
Rationale: Entamoeba histolytica is a parasitic protist known to cause amoebiasis, a gastrointestinal infection that can lead to symptoms such as foul-smelling diarrhea containing cysts. Upon microscopic examination of the feces, the presence of Entamoeba histolytica cysts is a key diagnostic feature. This parasite can be transmitted through contaminated food or water, and individuals infected with Entamoeba histolytica may experience abdominal pain, bloody diarrhea, and weight loss. Proper diagnosis and treatment are essential to manage this infection and prevent complications.

A patient presents with recurrent episodes of venous thrombosis, including deep vein thrombosis (DVT) and pulmonary embolism (PE), despite no apparent provoking factors. Which of the following conditions is most likely to cause these findings?
- A. Antithrombin III deficiency
- B. Protein C deficiency
- C. Protein S deficiency
- D. Factor V Leiden mutation
Correct Answer: D
Rationale: Factor V Leiden mutation is the most common inherited predisposition to venous thrombosis. In this condition, there is a specific mutation in the factor V gene (also known as factor V Leiden) that makes factor V resistant to inactivation by activated protein C. This resistance leads to excessive clot formation, increasing the risk of recurrent venous thrombosis like DVT and PE. Patients with Factor V Leiden mutation may have a history of recurrent unprovoked venous thrombosis at a young age. In comparison, antithrombin III deficiency, protein C deficiency, and protein S deficiency are other inherited thrombophilias that may increase the risk of venous thrombosis, but Factor V Leiden mutation is the most likely cause in this case based on the presentation of recurrent episodes without apparent provoking factors.
A 70- year-old has been rushed to the hospital due to bradycardia and palpitation. The physician suggested that a pacemaker be inserted to correct the symptoms. The patient voluntarily decides not to have the pacemaker Inserted. This is respected by the family. This is an example of what ethical principles

Rationale: Autonomy is the ethical principle that respects an individual's right to make their own decisions about their medical treatment, even if it goes against medical advice or the preferences of others. In this case, the 70-year-old patient has voluntarily decided not to have the pacemaker inserted despite the physician's recommendation. The fact that the patient's decision is respected by the family reflects the importance of honoring the patient's autonomy and right to make decisions about their own healthcare.
Amitriptyline, an antidepressant is the drug of choice in treating Bulimia. What is a COMMON side effect of this drug?
- A. Anticholinergic effects
- B. Cholinergic effects
- C. Urinary frequency
- D. Diarrhea
Correct Answer: A
Rationale: Amitriptyline, being a tricyclic antidepressant, commonly causes anticholinergic side effects. These effects include dry mouth, constipation, blurred vision, urinary retention, and confusion. Anticholinergic effects are due to the drug's inhibition of the neurotransmitter acetylcholine, which can lead to the symptoms mentioned above. These side effects can be bothersome for patients taking amitriptyline, but they are generally manageable and often improve over time as the body adjusts to the medication. In the case of bulimia treatment, the benefits of using amitriptyline to address the underlying psychological issues often outweigh the side effects.

A nurse is resistant to the change and is not taking an active part in facilitating the process of change. Which is the BEST approach in dealing with the nurse?
- A. Exert coercion on the nurse
- B. Provide a positive reward system for the nurse
- C. Talk and encourage verbalizing feelings of the change
- D. Ignore the resistance of the nurse.
Correct Answer: C
Rationale: The best approach in dealing with a nurse who is resistant to change and not actively participating is to communicate and encourage verbalizing feelings about the change. By talking with the nurse and allowing them to express their concerns and feelings, you can address any underlying issues that may be causing the resistance. This approach can help build trust, improve communication, and ultimately increase the nurse's engagement in the change process. Coercion (Choice A) can create negative feelings and resistance, while ignoring the nurse's resistance (Choice D) will not resolve the issue. Providing positive rewards (Choice B) may be helpful but may not address the underlying reasons for resistance. Communication is key in addressing resistance to change and fostering a positive, open environment for all involved.
