1. Which type of cells secrete insulin?

• A. alpha cells
• B. beta cells
• C. CD4 cells
• D. helper cells

Correct answer: B

Rationale: Beta cells are responsible for secreting insulin. Insulin is produced by beta cells in the pancreas and plays a crucial role in regulating blood sugar levels. Alpha cells secrete glucagon, not insulin (Choice A). CD4 cells are a type of immune cell that helps coordinate the immune response (Choice C). Helper cells are a type of immune cell that aids in activating other immune cells (Choice D). Therefore, the correct answer is beta cells.

2. The client has just returned from electroconvulsive therapy (ECT) and is very drowsy. What is the position of choice until the client regains full consciousness?

• A. Supine
• B. Fowlers
• C. Lateral
• D. High Fowlers

Correct answer: C

Rationale: The correct answer is 'Lateral.' When a client is very drowsy or sedated, placing them in the lateral position is important to maintain an open airway and allow for drainage of secretions. This position helps prevent airway obstruction and aspiration. Choice A, 'Supine,' is lying flat on the back and may not be ideal for a drowsy client due to the risk of airway compromise. Choice B, 'Fowlers,' is a semi-sitting position that is beneficial for clients with respiratory distress, but it may not be the best choice for a very drowsy individual. Choice D, 'High Fowlers,' is a more upright sitting position, which again may not be suitable for a drowsy client as it does not facilitate airway patency as effectively as the lateral position.

3. 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.

4. A nurse is working in a pediatric clinic, and a 25-year-old mother comes in with a 4-week-old baby. The mother is stressed out about the loss of sleep, and the baby exhibits signs of colic. Which of the following techniques should the nurse teach the mother?

• A. Distraction of the infant with a red object
• B. Prone positioning techniques
• C. Tapping reflex techniques
• D. Neural warmth techniques

Correct answer: D

Rationale: Neural warmth techniques involve the caregiver providing a warm, soothing touch to the baby, which can help to lower the baby's agitation level and promote relaxation. This technique is beneficial for calming colicky babies. Choices A, B, and C are incorrect because distraction with a red object, prone positioning, and tapping reflex techniques are not effective methods for managing colic in infants. Red object distraction is not a proven technique for soothing colicky babies. Prone positioning is not recommended for infants due to the risk of sudden infant death syndrome (SIDS). Tapping reflex techniques are not recognized as effective interventions for colic.

5. The nurse is caring for a client complaining of intense headaches with increasing pain for the past one month. An MRI is ordered. In reviewing the client's information, which piece of information is of concern?

• A. Allergy to shellfish
• B. Has a cardiac pacemaker
• C. A diabetic
• D. No IV access

Correct answer: B

Rationale: The correct answer is 'Has a cardiac pacemaker.' If a client with a cardiac pacemaker undergoes an MRI, the magnetic field can interfere with the pacemaker's function, leading to serious complications or even death. It is crucial to ensure that the pacemaker is compatible with MRI imaging or to consider alternative imaging modalities. The other choices, such as 'Allergy to shellfish,' 'A diabetic,' and 'No IV access,' are not direct contraindications for an MRI scan and do not pose the same level of risk as having a cardiac pacemaker.
