Proteins that are secreted by cells are generally
- A. not synthesized on membrane-bound ribosomes
- B. initially synthesized with a signal peptide or leader sequence at their C terminal
- C. found in vesicles and secretory granules
- D. moved across the cell membranes by endocytosis
Correct Answer: C
Rationale: Secreted proteins are typically synthesized on membrane-bound ribosomes and transported into the endoplasmic reticulum (ER) via a signal peptide at their N-terminal. They are then packaged into vesicles and secretory granules for transport to the cell membrane and release. Endocytosis is not involved in secretion, and proteins are usually processed (e.g., glycosylated) in the ER and Golgi, but they are not secreted in a larger form than in the ER.
Priority Decision: During assessment of a patient with a spinal cord injury, the nurse determines that the patient has a poor cough with diaphragmatic breathing. Based on this finding, what should be the nurse's first action?
- A. Institute frequent turning and repositioning
- B. Use tracheal suctioning to remove secretions
- C. Assess lung sounds and respiratory rate and depth
- D. Prepare the patient for endotracheal intubation and mechanical ventilation
Correct Answer: C
Rationale: Assessment ensures proper diagnosis before intervention.
The nurse practitioner conducting a neurological assessment on a patient uses a sterile cotton wisp to lightly touch the patient’s forehead, cheek, and chin. The nurse practitioner is testing the:
- A. Cranial nerve V (trigeminal)
- B. Cranial nerve VII (facial)
- C. Cranial nerve XII (hypoglossal)
- D. Cranial nerve II (optic)
Correct Answer: A
Rationale: The correct answer is A: Cranial nerve V (trigeminal). The nurse practitioner is testing the trigeminal nerve's sensory function by using a sterile cotton wisp to assess light touch sensation in the patient's forehead, cheek, and chin. The trigeminal nerve has three branches - ophthalmic, maxillary, and mandibular - which innervate these areas respectively. By assessing the patient's response to the light touch in these specific areas, the nurse practitioner can determine if the sensory function of the trigeminal nerve is intact.
Summary:
B: Cranial nerve VII (facial) controls facial expression, not sensation.
C: Cranial nerve XII (hypoglossal) controls tongue movement, not facial sensation.
D: Cranial nerve II (optic) is responsible for vision, not facial sensation.
Which cranial nerve lies in the junction between pons and medilla?
- A. abducent nerve (VI)
- B. facial nerve (VII)
- C. vestibulocochlear nerve (VIII)
- D. glossopharyngeal nerve (IX)
Correct Answer: A
Rationale: The abducent nerve (VI) emerges at the junction between the pons and medulla. It controls the lateral rectus muscle, which abducts the eye.

- B. The side effects and interactions of the medications.
- C. Symptoms that necessitate a call to the physician, nurse practitioner, or physician assistant.
- D. All of the above.
Correct Answer: D
Rationale: All aspects mentioned are crucial for effective post-discharge care and prevention of complications.
