Which of the following structures is responsible for the production of saliva, which aids in lubricating the oral cavity and initiating the digestion of carbohydrates?
- A. Liver
- B. Gallbladder
- C. Salivary glands
- D. Pancreas
Correct Answer: C
Rationale: The salivary glands are responsible for the production of saliva, which aids in lubricating the oral cavity and initiating the digestion of carbohydrates. Saliva contains enzymes that begin the digestive process by breaking down carbohydrates into simpler sugars. The liver is involved in the production of bile, which aids in the digestion and absorption of fats. The gallbladder stores bile produced by the liver, which is released into the small intestine. The pancreas produces digestive enzymes that are released into the small intestine to aid in the digestion of proteins, fats, and carbohydrates.

A woman in active labor is experiencing a shoulder dystocia during delivery. What nursing intervention should be prioritized?
- A. Apply suprapubic pressure to dislodge the shoulder.
- B. Perform an episiotomy to facilitate delivery.
- C. Insert an oropharyngeal airway to maintain airway patency.
- D. Administer intravenous magnesium sulfate for uterine relaxation.
Correct Answer: A
Rationale: Shoulder dystocia is an obstetric emergency where one of the baby's shoulders becomes impacted behind the mother's pubic bone after the head delivers. This can lead to compression of the umbilical cord and compromise fetal oxygenation. The most critical nursing intervention in managing shoulder dystocia is applying suprapubic pressure to dislodge the impacted shoulder and allow for delivery of the baby. By gently pushing downwards on the mother's abdomen just above the pubic bone, the shoulder can be released, and the baby can be delivered successfully. This intervention should be prioritized to prevent potential complications for both the mother and the baby. Episiotomy may be considered if necessary, but it is secondary to addressing the shoulder dystocia. Oropharyngeal airway insertion and administering magnesium sulfate are not indicated in the immediate management of shoulder dystocia.
In order to determine the patient's ability to concentrate and focus, which would be the PRIORITY nursing action?
- A. Asked for the academic performance
- B. Conduct paper and pencil test
- C. Assess the mental status of the patient
- D. Refer the patient to the psychiatrist
Correct Answer: C
Rationale: Assessing the mental status of the patient is the PRIORITY nursing action to determine the patient's ability to concentrate and focus. This assessment includes evaluating the patient's level of alertness, orientation, memory, thought processes, and mood. By observing the patient's mental status, the nurse can gain valuable information about the patient's cognitive function, attention span, and ability to concentrate. This assessment will help guide further interventions and care planning for the patient. Asking for academic performance or conducting paper and pencil tests may be useful tools to assess concentration and focus, but they should come after a comprehensive evaluation of the patient's mental status. Referring the patient to a psychiatrist may be necessary based on the assessment findings, but it should not be the first step in determining the patient's ability to concentrate and focus.
A patient presents with recurrent episodes of epistaxis, particularly after blowing the nose or during dry weather. Anterior rhinoscopy reveals a friable, vascular lesion in Little's area. Which of the following interventions is most appropriate for managing this condition?
- A. Nasal packing with anterior nasal tampons
- B. Application of silver nitrate cautery
- C. Endoscopic cauterization of the sphenopalatine artery
- D. Surgical excision of the nasal polyp
Correct Answer: B
Rationale: The clinical scenario described is consistent with a diagnosis of anterior epistaxis due to a prominent vascular lesion located in Little's area, which is an important site for nosebleeds. Silver nitrate cautery is the most appropriate intervention for managing this condition. Silver nitrate cautery is a commonly used method to chemically cauterize and eliminate the friable blood vessels responsible for recurrent epistaxis. It is a cost-effective and minimally invasive technique that can be easily performed in an outpatient setting. Nasal packing with anterior nasal tampons might be considered in cases of severe or refractory epistaxis, but in this scenario, where the source of bleeding is localized and identifiable, silver nitrate cautery is the treatment of choice. Endoscopic cauterization of the sphenopalatine artery and surgical excision of a nasal polyp are unnecessary and overly invasive for the described scenario.
Which of the following manifestation should the nurse APPROPRIATELY observe during generalized seizures?
- A. Loss of Consciousness, dilated pupils, and muscular stiffening
- B. Jerking movements of al1 extremities.
- C. Facial grimace with patting and smacking.
- D. Vacant stare with a brief Loss of consciousness
Correct Answer: A
Rationale: Generalized seizures involve both hemispheres of the brain and can present with various manifestations. The typical features of generalized seizures include loss of consciousness, dilated pupils, and muscular stiffening. These seizures may also involve other symptoms such as tonic-clonic movements, convulsions, and postictal confusion. Jerking movements of all extremities (option B) are more characteristic of tonic-clonic seizures, a subtype of generalized seizures. Facial grimace with patting and smacking (option C) may be seen in focal seizures originating from a certain area of the brain. A vacant stare with a brief loss of consciousness (option D) is more typical of absence seizures rather than generalized seizures.
and tumor necrosis factor-alpha (TNF-α) during the acute phase response?
- A. Macrophages
- B. T lymphocytes
- C. B lymphocytes
- D. Natural killer (NK) cells
Correct Answer: A
Rationale: Macrophages are the primary cells responsible for producing tumor necrosis factor-alpha (TNF-α) during the acute phase response. TNF-α is a pro-inflammatory cytokine that plays a critical role in initiating and propagating the inflammatory response. Macrophages secrete TNF-α in response to infection, injury, or other inflammatory stimuli, contributing to the recruitment of immune cells and the activation of additional inflammatory pathways. In the context of the acute phase response, macrophages are key mediators of the immune response and play a crucial role in host defense mechanisms.
