Nursing Elites

1. A client with a diagnosis of depression has been prescribed a medication that ultimately increases the levels of the neurotransmitter serotonin between neurons. Which process will accompany the actions of the neurotransmitter in a chemical synapse?

• A. Two-way communication between neurons is permitted, in contrast to the one-way communication in electrical synapses.
• B. Communication between a neuron and the single neuron it is connected with will be facilitated.
• C. The neurotransmitter will cross gap junctions more readily.
• D. More neurotransmitters will cross the synaptic cleft and bond with postsynaptic receptors.

Correct answer: D

Rationale: When serotonin levels increase, more neurotransmitters will cross the synaptic cleft and bind with postsynaptic receptors, facilitating enhanced communication. Option A is incorrect because chemical synapses, unlike electrical synapses, are unidirectional. Option B is incorrect because neurotransmitters impact communication with multiple neurons, not just a single connected neuron. Option C is incorrect because neurotransmitters cross the synaptic cleft, not gap junctions.

2. An infant is being administered an immunization. Which of the following provides an accurate description of an immunization?

• A. It should be administered to a pregnant woman prior to the infant's birth.
• B. It is the administration of an antigen to stimulate an antibody response.
• C. It produces many adverse reactions, particularly autism, in the infant.
• D. It protects the infant from exposure to infectious antibodies.

Correct answer: B

Rationale: The correct answer is B. Immunization involves administering an antigen, such as a weakened or killed microorganism, to stimulate the immune system to produce an antibody response. This process helps the body recognize and remember specific pathogens, providing immunity against future infections. Choice A is incorrect because immunizations are administered to the infant directly, not to the pregnant woman before birth. Choice C is incorrect as there is no scientific evidence linking immunizations to autism. Choice D is incorrect as immunizations protect against infectious agents, not antibodies.

3. A male patient is receiving testosterone therapy for hypogonadism. What adverse effect should the nurse monitor during this therapy?

• A. Increased risk of cardiovascular events
• B. Increased risk of liver dysfunction
• C. Increased risk of prostate cancer
• D. Increased risk of bone fractures

Correct answer: A

Rationale: The correct answer is A: Increased risk of cardiovascular events. Testosterone therapy can lead to an increased risk of cardiovascular events like heart attacks and strokes, especially in older patients. Choice B, increased risk of liver dysfunction, is not a common adverse effect of testosterone therapy. Choice C, increased risk of prostate cancer, is a concern when using testosterone therapy in patients with existing prostate cancer, but not a general adverse effect. Choice D, increased risk of bone fractures, is not typically associated with testosterone therapy.

4. What tool is used to determine a client’s level of consciousness?

• A. Magnetic resonance imaging (MRI)
• B. Glasgow Coma Scale (GCS)
• C. Central perfusion pressure (CPP)
• D. Intracranial pressure (ICP) monitoring

Correct answer: B

Rationale: The correct answer is B: Glasgow Coma Scale (GCS). The Glasgow Coma Scale is specifically designed to assess a client's level of consciousness by evaluating verbal, motor, and eye-opening responses. Choice A, Magnetic Resonance Imaging (MRI), is a diagnostic imaging tool that provides detailed images of the body's organs and tissues but is not used to assess consciousness levels. Choice C, Central Perfusion Pressure (CPP), and Choice D, Intracranial Pressure (ICP) monitoring, are related to hemodynamic monitoring and intracranial pressure management, not direct assessment of consciousness.

5. In nephritic syndrome compared to nephrotic syndrome, there is:

• A. higher amounts of albuminuria.
• B. negligible hematuria or absence of hematuria.
• C. presence of red blood cell casts in the urine.
• D. hypoalbuminemia

Correct answer: C

Rationale: In nephritic syndrome, the presence of red blood cell casts in the urine is a characteristic finding, reflecting glomerular inflammation and damage. This differentiates it from nephrotic syndrome, where red blood cell casts are typically absent. Choice A is incorrect because nephritic syndrome usually presents with less albuminuria compared to nephrotic syndrome. Choice B is incorrect as hematuria is a common feature of nephritic syndrome. Choice D is incorrect as hypoalbuminemia is more commonly associated with nephrotic syndrome.
