Which of the following parts of neuron transmits impulses away from the cell body?

Correct Answer: C

Rationale: The correct answer is C: Axon. The axon is the part of the neuron that transmits impulses away from the cell body towards other neurons, muscles, or glands. Its structure allows for the rapid transmission of electrical signals. Rationale: 1. Dendrites receive signals and transmit them towards the cell body, so A is incorrect. 2. Neurolemma is the outermost layer of a Schwann cell, not a part of the neuron responsible for transmitting impulses, so B is incorrect. 3. The synapse is the junction between two neurons where communication occurs, not a part of the neuron transmitting impulses, so D is incorrect.

Correct Answer: D

Rationale: Step 1: The DASH diet is specifically designed to help lower blood pressure, making it the most appropriate choice for clients with hypertension. Step 2: The DASH diet emphasizes fruits, vegetables, whole grains, lean proteins, and low-fat dairy, all of which are beneficial for managing hypertension. Step 3: The diet also limits sodium intake, which is crucial for controlling blood pressure. Step 4: The other options (A, B, and C) do not have the same evidence-based focus on hypertension management and may not be as effective in lowering blood pressure.

Correct Answer: B

Rationale: The correct answer is B: The potential complication. In a collaborative problem, the focus of a diagnostic statement should be on identifying potential complications that may arise due to the client's health issue. This is important for developing effective interventions to prevent or manage these complications. Choice A focuses on the client's problem itself, not on potential complications. Choice C is related to nursing diagnosis, not collaborative problems. Choice D refers to medical diagnosis, which is different from collaborative problems involving nursing and other healthcare disciplines. Therefore, B is the correct focus for a diagnostic statement in a collaborative problem scenario.

Correct Answer: C

Rationale: The correct answer is C: Collaborative problem. In the given diagnostic statement, "Impaired physical mobility related to tibial fracture as evidenced by patient’s inability to ambulate," the nurse needs to revise the mention of collaborative problem. The collaborative problem is a health issue that requires the expertise of multiple healthcare providers, whereas the statement provided focuses on a nursing diagnosis related to physical mobility impairment. The etiology (cause), nursing diagnosis, and defining characteristic are all relevant to the nursing diagnostic statement and do not need revision. The collaborative problem aspect is not appropriate in this context as it does not fit the criteria for a collaborative problem.

Correct Answer: D

Rationale: The correct answer is D: pain in the scapular region. This is because a herniated nucleus pulposus at the C4-C5 and C5-C6 interspaces typically results in pain radiating from the neck to the scapular region due to nerve compression at those levels. The other choices are incorrect as constant, throbbing headaches are not typically associated with this specific diagnosis, clonus in the lower extremities is more indicative of lower spinal cord involvement, and numbness of the face is not a common symptom of herniated discs at these levels.

Correct Answer: C

Rationale: The correct answer is C: severe dehydration. In HHNK coma, the body tries to eliminate excess glucose through frequent urination, leading to dehydration. This results in decreased blood volume, causing hypotension and tachycardia. Signs include dry mucous membranes, poor skin turgor, and concentrated urine output. Fruity odor of the breath (A) is associated with diabetic ketoacidosis, not HHNK coma. Shallow, deep respirations (B) and profuse sweating (D) are not typically associated with HHNK coma.

Correct Answer: B

Rationale: The correct answer is B: A hypothermia blanket. This is important because hypothermia can lead to complications such as shivering, increased risk of infection, and altered drug metabolism. Checking for the hypothermia blanket ensures Mrs. Zeno's temperature is regulated, promoting safety. A: A tracheostomy set is not directly related to Mrs. Zeno's immediate safety unless she has a tracheostomy in place. C: An intravenous set-up is important for administering medications, fluids, or blood products, but it is not directly related to Mrs. Zeno's safety at the bedside. D: A syringe and edrophonium HCl(Tensilon) is specific to a diagnostic test for myasthenia gravis, which may not be relevant to Mrs. Zeno's current condition or safety.

Correct Answer: C

Rationale: The correct answer is C: 0.90% sodium chloride. When administering a hypotonic solution like 0.45% sodium chloride or 5% dextrose in water, water moves into the cells causing them to swell. This can exacerbate symptoms of hypovolemia such as low blood pressure and decreased perfusion. However, 0.90% sodium chloride is an isotonic solution and will not further exacerbate hypovolemic symptoms. Choices A, B, and D are hypotonic solutions that can worsen hypovolemic symptoms by causing cellular swelling.

Correct Answer: C

Rationale: The correct answer is C: Collaborative problem. The nurse needs to revise the collaborative problem part of the diagnostic statement because impaired physical mobility related to tibial fracture is a nursing diagnosis, not a collaborative problem. A collaborative problem involves potential complications that require both nursing and medical interventions. In this case, impaired physical mobility is a nursing diagnosis that requires nursing interventions to address the patient's inability to ambulate. Choices A, B, and D are incorrect because they are all relevant components of a nursing diagnostic statement: A - Etiology identifies the cause of the nursing diagnosis, B - Nursing diagnosis states the health problem, and D - Defining characteristic provides evidence supporting the nursing diagnosis.
