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 a displaced fracture of the distal radius and ulna after a fall. What is the preferred initial treatment for this injury?
- A. Closed reduction and splinting
- B. Open reduction and internal fixation (ORIF)
- C. Closed reduction and external fixation (CREF)
- D. Cast immobilization without reduction
Correct Answer: A
Rationale: In the case of a displaced fracture of the distal radius and ulna, the preferred initial treatment is typically closed reduction and splinting. Closed reduction involves manually realigning the fractured bones without the need for surgery. Splinting is then utilized to immobilize the wrist and forearm to allow for proper healing of the fracture. This approach is often effective in realigning the bones and stabilizing the injury, allowing for adequate healing without the need for more invasive interventions like surgery. Following the initial management with closed reduction and splinting, the patient's progress will be monitored, and further interventions may be considered based on the specific characteristics of the fracture and the patient's response to treatment.
A client is being prepared for a thoracentesis. The nurse should assist the client to which position for the procedure?
- A. Lying in bed on the affected side
- B. Lying in bed on the unaffected side
- C. Sims position with the head of the bed flat
- D. Prone with the head turned to the side and supported by a pillow
Correct Answer: B
Rationale: The client should be assisted to lie in bed on the unaffected side for a thoracentesis procedure. This position allows for better access to the pleural space for the insertion of a needle to aspirate the fluid or air. Gravity helps to separate the fluid or air, making it closer to the chest wall for easier removal. Additionally, this position reduces the risk of injury to the lung or other structures, as the needle is directed away from these vital structures. Lying on the unaffected side also helps in preventing potential complications and ensures the safety and effectiveness of the procedure.
Dina is taking human Insulin injection for diabetes. Which of the following health instructions should you APPROPRIATELY emphasized in order to avoid hypoglycemia? Inject insulin into the _______.
- A. Anterior part of the leg muscle intramuscularly
- B. Gluteal region subcutaneously and rotate
- C. Abdominal wall subcutaneously and then rotate
- D. Deltoid muscle intramuscularly and rotate
Correct Answer: C
Rationale: The appropriate and recommended site for insulin injection to help avoid hypoglycemia is the abdominal wall subcutaneously. This site offers a consistent and reliable rate of absorption of insulin into the bloodstream. By injecting insulin into the abdominal wall subcutaneously, it allows for better control of blood sugar levels and reduces the risk of hypoglycemia. Additionally, it is important to rotate injection sites within the chosen area to prevent the development of lipohypertrophy (thickened, rubbery areas under the skin), which can affect insulin absorption.
The nurse closely monitors the work she delegated to the barangay health worker. She is legally guided by this principle
- A. Respondent superior
- B. The good Samaritan
- C. Res ipsa loquitor
- D. Jurisprudence
Correct Answer: A
Rationale: Respondent superior is a legal doctrine that holds an employer (such as a nurse) responsible for the actions of their employees (such as a barangay health worker) performed within the scope of their employment. In the scenario provided, the nurse delegated tasks to the barangay health worker, making the health worker an agent of the nurse. By closely monitoring the delegated work, the nurse is fulfilling her legal responsibility under the principle of respondent superior to ensure that the health worker performs their duties properly and in accordance with professional standards.
The nurse is conducting an assessment to her patient who has edema of the lower extremities due to congestive heart failure. If edema is graded on a scale of +1 (no visible edema in the leg) to 4+ (leg very swollen), what will the Nurse document in her chart if her assessment findings of the edema is SLIGHTLY swollen?
- A. 4
- B. 2
- C. 1
- D. 3
Correct Answer: B
Rationale: In the grading system used for edema, +1 indicates no visible edema in the leg, +2 indicates slight edema with indentations that quickly resolve, +3 indicates moderate edema with deeper indentations that may take longer to resolve, and +4 indicates severe edema with very swollen legs. In this case, since the edema is described as slightly swollen, the appropriate grade to document would be +2.
