Which of the following salivary glands is located inferior and posterior to the mandible and produces serous saliva rich in enzymes?
- A. Parotid gland
- B. Sublingual gland
- C. Submandibular gland
- D. Submaxillary gland
Correct Answer: C
Rationale: The submandibular gland is located inferior and posterior to the mandible. It produces a mixed type of saliva, which is primarily serous (enzyme-rich) but also contains some mucous components. This gland plays a significant role in digestion, as its serous saliva contains enzymes such as amylase that help break down carbohydrates in the mouth before they reach the stomach.

One GOOD nursing intervention of the nurse for Almira would be to do which of the following?
- A. Advise her to eat her meals.
- B. Put her on absolute bed rest.
- C. Take the vital signs q 4 hours.
- D. Advise her to take care of Jay.
Correct Answer: A
Rationale: The correct nursing intervention for Almira would be to advise her to eat her meals. This is important in promoting her health and well-being, especially if she has been neglecting her own nutrition due to stress or caring for her son, Jay. Providing proper nutrition is a basic aspect of nursing care that supports the overall health and recovery of the patient. By encouraging Almira to prioritize her own nutrition, the nurse can help ensure that she has the physical strength and energy needed to take care of herself and her son effectively.
A patient presents with a pruritic rash with linear streaks and small, fluid-filled blisters. The patient reports recent exposure to poison ivy while gardening. Which of the following conditions is most likely responsible for this presentation?
- A. Pemphigus vulgaris
- B. Allergic contact dermatitis
- C. Bullous pemphigoid
- D. Herpes zoster (shingles)
Correct Answer: B
Rationale: The presentation of a pruritic rash with linear streaks and small, fluid-filled blisters following exposure to poison ivy is characteristic of allergic contact dermatitis. Poison ivy contains an oil called urushiol, which is known to cause this type of skin reaction in individuals who are sensitive to it. The linear streaks are often a result of the plant brushing against the skin. Pemphigus vulgaris is an autoimmune condition characterized by the formation of intraepidermal blisters, typically not associated with linear streaks or exposure to irritants like poison ivy. Bullous pemphigoid is characterized by subepidermal blisters, and herpes zoster presents with a painful rash following reactivation of the varicella-zoster virus in a dermatomal pattern, not typically in linear streaks.
Nurse Vera informs the patient she should be screened for pre-eclmapsia during this term of pregnancy_______.
- A. first
- B. Third
- C. second
- D. Before delivery
Correct Answer: A
Rationale: Pre-eclampsia is a serious condition that can occur during pregnancy, usually after 20 weeks gestation. It is important to screen for pre-eclampsia early in the pregnancy to monitor and manage the condition effectively. Screening for pre-eclampsia typically begins in the first trimester of pregnancy to identify any risk factors and provide appropriate care for the patient. Therefore, Nurse Vera informing the patient to get screened for pre-eclampsia in the first term of pregnancy is the most appropriate time to start monitoring for this condition.
Which procedure has to be done to the patient to establish a definitive diagnosis of lung cancer?
- A. Chest x-ray followed by a CT scan
- B. Cytological study of the sputum
- C. Bronchoscopy
- D. Magnetic resonance imaging
Correct Answer: C
Rationale: Bronchoscopy is a procedure that allows direct visualization of the inside of the airways in the lungs. It is considered the most definitive method to establish a diagnosis of lung cancer as it can directly visualize any abnormal growths or tumors in the bronchial tubes. During bronchoscopy, tissue samples can be collected for biopsy to confirm the presence of cancer cells. This procedure is more accurate compared to other diagnostic methods such as chest x-ray, CT scan, cytological study of sputum, or magnetic resonance imaging in confirming a diagnosis of lung cancer.
Which of the following statements accurately describes the role of dendritic cells in the immune response?
- A. Dendritic cells directly kill infected cells and tumor cells.
- B. Dendritic cells produce antibodies against pathogens.
- C. Dendritic cells activate na(cid:239)ve T cells and initiate adaptive immune responses.
- D. Dendritic cells release histamine and other inflammatory mediators.
Correct Answer: C
Rationale: Dendritic cells play a critical role in initiating adaptive immune responses by capturing antigens from pathogens, migrating to lymphoid organs, and presenting these antigens to naïve T cells. This activation of naïve T cells by dendritic cells is essential for the adaptive immune system to generate specific immune responses against pathogens. Dendritic cells act as professional antigen-presenting cells, which are specialized to capture, process, and present antigens to T cells, thereby facilitating the activation of T cells and the coordination of adaptive immune responses, such as the production of specific antibodies and the generation of memory T cells.
