1. A nurse is caring for a patient in the step-down unit. The patient has signs of increased intracranial pressure. Which of the following is not a sign of increased intracranial pressure?

A. Bradycardia
B. Increased pupil size bilaterally
C. Change in LOC
D. Vomiting

Correct answer: B

Rationale: The correct answer is 'Increased pupil size bilaterally.' When assessing for signs of increased intracranial pressure, bilateral pupil dilation is not typically associated with this condition. Instead, unilateral pupil changes, especially one pupil becoming dilated or non-reactive while the other remains normal, are indicative of increased ICP. Bradycardia, a change in level of consciousness (LOC), and vomiting are commonly seen in patients with increased intracranial pressure due to the brain's response to the rising pressure. Therefore, the presence of bilateral pupil dilation goes against the typical pattern observed in patients with increased intracranial pressure.

2. 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.

3. Which of the following organs of the digestive system has a primary function of absorption?

A. stomach
B. pancreas
C. small intestine
D. gallbladder

Correct answer: C

Rationale: The small intestine is the correct answer. It is the primary organ responsible for absorption in the digestive system. The stomach's primary function is to break down food through mechanical and chemical digestion. The pancreas produces digestive enzymes to aid in the breakdown of food. The gallbladder stores bile produced by the liver, which helps in the digestion of fats. However, neither the stomach, pancreas, nor gallbladder play the primary role of absorption in the digestive process, making them incorrect choices.

4. What is the best lab test to diagnose disseminated intravascular coagulation (DIC)?

A. platelet count
B. prothrombin time (PT)
C. partial thromboplastin time (PTT)
D. D-dimer

Correct answer: D

Rationale: The best lab test to diagnose disseminated intravascular coagulation (DIC) is the D-dimer test. In DIC, numerous small clots form throughout the body and are rapidly broken down. D-dimer measures a specific fibrin split product and is the most specific test for DIC. Platelet count (Choice A) is decreased in DIC due to consumption, but it is not specific for diagnosing DIC. Prothrombin time (PT - Choice B) and partial thromboplastin time (PTT - Choice C) are both elevated in DIC because clotting factors have been used up, but they are not specific for DIC as they can be elevated in other conditions as well.

5. Which client should the nurse see first?

A. Recurring crushing chest pain
B. Needing an IV for surgery in 5 minutes
C. Needing PCA morphine for pain control post-hysterectomy
D. Waiting to get back to bed after sitting in a chair for 30 minutes

Correct answer: A

Rationale: The client presenting with recurring crushing chest pain should be seen first as this symptom could indicate a myocardial infarction (MI), which is a life-threatening condition requiring immediate attention. Assessing and managing potential cardiac issues take priority over other concerns like needing an IV for surgery, pain control post-hysterectomy, or assistance with mobility. While all clients require care, addressing the chest pain promptly is crucial to ensure the client's safety and well-being.
