Which of the following structures is responsible for the production of digestive enzymes and bicarbonate-rich pancreatic juice?
- A. Liver
- B. Gallbladder
- C. Pancreas
- D. Spleen
Correct Answer: C
Rationale: The correct answer is C: Pancreas. The pancreas is responsible for producing digestive enzymes and bicarbonate-rich pancreatic juice. It secretes enzymes like amylase, lipase, and protease to break down carbohydrates, fats, and proteins in the small intestine. The bicarbonate-rich juice helps neutralize stomach acid. The liver (A) produces bile stored in the gallbladder (B), which aids in fat digestion. The spleen (D) is involved in immune function and blood filtration, not digestive enzyme production.

A patient in the ICU develops acute exacerbation of chronic obstructive pulmonary disease (COPD) characterized by worsening dyspnea and increased sputum production. What intervention should the healthcare team prioritize to manage the patient's exacerbation?
- A. Administer bronchodilator medications via nebulization for bronchodilation.
- B. Initiate non-invasive positive pressure ventilation (NIPPV) for respiratory support.
- C. Perform arterial blood gas analysis to assess oxygenation and ventilation.
- D. Recommend chest physiotherapy to promote airway clearance.
Correct Answer: B
Rationale: The correct answer is B: Initiate non-invasive positive pressure ventilation (NIPPV) for respiratory support. In acute exacerbations of COPD, NIPPV helps improve ventilation and oxygenation, reducing the work of breathing and preventing the need for intubation. This intervention is a priority as it can rapidly stabilize the patient's respiratory status.
A: Administering bronchodilator medications is important in COPD management, but in severe exacerbations, NIPPV takes precedence.
C: Arterial blood gas analysis is important for assessing oxygenation and ventilation status, but it does not directly address the acute respiratory distress.
D: Chest physiotherapy can help with airway clearance in COPD, but in acute exacerbations, respiratory support with NIPPV is more urgent.
A patient presents with pruritic, erythematous patches with silvery scales on the elbows, knees, and scalp. Which of the following conditions is most likely responsible for this presentation?
- A. Eczema
- B. Psoriasis
- C. Pityriasis rosea
- D. Seborrheic dermatitis
Correct Answer: B
Rationale: The correct answer is B: Psoriasis. Psoriasis is characterized by pruritic, erythematous patches with silvery scales, commonly found on the elbows, knees, and scalp. This presentation matches the patient's symptoms. Eczema (choice A) typically presents with red, inflamed, and itchy skin patches. Pityriasis rosea (choice C) manifests as a herald patch followed by smaller scaly patches in a "Christmas tree" distribution. Seborrheic dermatitis (choice D) involves oily, yellowish, scaly patches mainly on the scalp, face, and ears, and does not typically present with silvery scales.
A patient presents with redness, pain, and photophobia in the left eye. Slit-lamp examination reveals ciliary injection, corneal edema, and a mid-dilated pupil with fixed reaction to light. Which of the following conditions is most likely responsible for this presentation?
- A. Anterior uveitis
- B. Acute angle-closure glaucoma
- C. Endophthalmitis
- D. Corneal abrasion
Correct Answer: A
Rationale: The correct answer is A: Anterior uveitis. This condition presents with redness, pain, and photophobia due to inflammation of the uveal tract. Ciliary injection, corneal edema, and mid-dilated pupil with fixed reaction to light are classic signs of anterior uveitis. The other choices can be ruled out based on specific findings: B: Acute angle-closure glaucoma would present with a high intraocular pressure, not fixed dilated pupil. C: Endophthalmitis typically presents with severe pain, hypopyon, and vitreous inflammation. D: Corneal abrasion would not cause ciliary injection or fixed dilated pupil.
When a person vaccinated with a Covid-19 vaccine produces antibodies to the disease, the immunity is termed:
- A. Active artificial
- B. Active natural
- C. Passive natural
- D. Passive artificial
Correct Answer: A
Rationale: The correct answer is A: Active artificial immunity. This is because the person's immune system is actively stimulated by the vaccine to produce antibodies against Covid-19. It is considered artificial because it is acquired through vaccination rather than natural exposure to the disease.
B: Active natural immunity is incorrect because it refers to immunity acquired through natural exposure to the disease.
C: Passive natural immunity is incorrect because it refers to temporary immunity passed from mother to baby through breast milk or placenta.
D: Passive artificial immunity is incorrect because it refers to receiving pre-formed antibodies, such as through an injection of antibodies rather than the body producing them itself.
Outbreak of cases of typhoid fever occurs in the community. Nurse Keena should inform the residents that the transmission of the disease is through _______.
- A. A vector
- B. Blood and body fluids
- C. Food and water
- D. Air
Correct Answer: C
Rationale: The correct answer is C: Food and water. Typhoid fever is primarily transmitted through contaminated food and water by the bacterium Salmonella typhi. The bacteria are shed in the feces of infected individuals and can contaminate water sources or food prepared with contaminated water. This transmission route aligns with the typical epidemiology of typhoid fever outbreaks.
Now, let's discuss why the other choices are incorrect:
A: A vector - Typhoid fever is not transmitted by a vector such as mosquitoes or ticks.
B: Blood and body fluids - Typhoid fever is not typically spread through blood or body fluids but rather through ingestion of contaminated food or water.
D: Air - Typhoid fever is not an airborne disease and is not transmitted through the air.
