What type of cells create exocrine secretions?
- A. alpha cells
- B. beta cells
- C. acinar cells
- D. plasma cells
Correct Answer: C
Rationale: Acinar cells are responsible for creating exocrine secretions, such as enzymes and digestive juices. Alpha cells are found in the pancreas and are responsible for producing glucagon, beta cells produce insulin, and plasma cells are a type of white blood cell involved in immune responses. Therefore, the correct answer is acinar cells, as they specifically produce exocrine secretions.

A 64-year-old Alzheimer's patient has exhibited excessive cognitive decline resulting in harmful behaviors. The physician orders restraints to be placed on the patient. Which of the following is the appropriate procedure?
- A. Secure the restraints to the bed rails on all extremities.
- B. Notify the physician that restraints have been placed properly.
- C. Communicate with the patient and family the need for restraints.
- D. Position the head of the bed at a 45-degree angle.
Correct Answer: C
Rationale: In cases where restraints are considered necessary for a patient, it is crucial to communicate effectively with both the patient and their family about the reasons for this decision. This helps ensure that all parties involved understand the necessity of restraints and are informed about the potential risks and benefits. Option A, securing restraints to the bed rails on all extremities, is not appropriate as it does not involve proper communication or ethical considerations. Option B, notifying the physician that restraints have been placed properly, overlooks the importance of patient and family involvement in decision-making. Option D, positioning the head of the bed at a 45-degree angle, is unrelated to the use of restraints and does not address the situation at hand.
A nurse has been ordered to set up Buck's traction on a patient's lower extremity due to a femur fracture. Which of the following applies to Buck's traction?
- A. A weight greater than 10 lbs. should be used.
- B. The line of pull is upward at an angle.
- C. The line of pull is straight
- D. A weight greater than 20 lbs. should be used.
Correct Answer: C
Rationale: The correct answer is that the line of pull is straight for Buck's traction. This type of traction is applied to maintain alignment and immobilization of fractures, typically involving the lower extremities. A straight line of pull helps to provide the necessary countertraction to keep the fractured bone in proper alignment. Choices A and D are incorrect because Buck's traction commonly uses a weight range between 5-10 lbs, and using a weight greater than 10 or 20 lbs would not be appropriate or safe. Choice B is incorrect as well since the line of pull for Buck's traction is straight, not upward at an angle.
During a screening on a patient with a recent cast on the left lower extremity, which of the following statements should the nurse be most concerned about?
- A. The patient reports, "I didn't keep my extremity elevated as the doctor asked me to."?
- B. The patient reports, "I have been having pain in my left calf."?
- C. The patient reports, "My left leg has really been itching."?
- D. The patient reports, "The arthritis in my wrists is flaring up when I put weight on my crutches."?
Correct Answer: B
Rationale: The correct answer is B because pain in the left calf could indicate a potential neurovascular complication related to the casted extremity. It could suggest issues such as compartment syndrome or impaired circulation. Option A is not as concerning since not elevating the extremity may lead to swelling but is not an immediate concern. Option C indicates itching, which is common with casts and not as concerning as potential neurovascular issues. Option D, regarding arthritis in the wrists, is unrelated to the lower extremity issue being screened for.
A 32-year-old male with a complaint of dizziness has an order for Morphine via IV. What should the nurse do first?
- A. Check the patient's chest x-ray results.
- B. Retake vitals including blood pressure.
- C. Perform a neurological screening on the patient.
- D. Request the physician on-call to assess the patient.
Correct Answer: B
Rationale: The correct first action for the nurse to take in this situation is to retake the patient's vitals, including blood pressure. Dizziness can be a sign of hypotension, which may be a contraindication for administering Morphine. Checking the chest x-ray results (Choice A) would not be the priority in this case as addressing the dizziness is more urgent. Performing a neurological screening (Choice C) may be important but not the first step when a patient presents with dizziness and an order for Morphine. Requesting the physician to assess the patient (Choice D) should come after the initial assessment and vitals retake.
A patient has recently been prescribed Norvasc. Which of the following side effects should the patient specifically watch out for?
- A. Hypotension and Angina
- B. Hypertension
- C. Lower extremity edema
- D. Peripheral sensory loss and SOB
Correct Answer: A
Rationale: The correct answer is 'Hypotension and Angina.' Norvasc is a medication known to cause hypotension (low blood pressure) and angina (chest pain) as side effects. These side effects are important for the patient to watch out for as they can indicate potential issues related to the medication. Choice B ('Hypertension') is incorrect as Norvasc is actually used to treat hypertension, not cause it. Choice C ('Lower extremity edema') is not a common side effect of Norvasc. Choice D ('Peripheral sensory loss and SOB') is not typically associated with Norvasc's side effects.
