Question 1 of 9
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 or target cells. It is coated with a myelin sheath, which helps speed up the transmission of impulses. Dendrites (A) receive signals from other neurons, the neurolemma (B) is the outermost layer of the myelin sheath, and the synapse (D) is the junction between two neurons where neurotransmitters are released. Therefore, the axon is the only part of the neuron specifically responsible for transmitting impulses away from the cell body.
Question 2 of 9
Which drug class is used to reduce symptoms of muscle weakness from myasthenia gravis?
Correct Answer: A
Rationale: The correct answer is A: Anticholinesterase drugs. These drugs increase acetylcholine levels at neuromuscular junctions, helping improve muscle strength in myasthenia gravis. Adrenergic drugs (B) and beta-blocker drugs (D) are not typically used to treat muscle weakness in myasthenia gravis. Anticholinergic drugs (C) can worsen symptoms by blocking acetylcholine receptors, making them an inappropriate choice for this condition.
Question 3 of 9
What are the periods in life when the need for iron increases?
Correct Answer: A
Rationale: The correct answer is A: Pregnancy. During pregnancy, the need for iron increases significantly to support the growth of the fetus and to prevent maternal anemia. Iron is essential for the production of hemoglobin and for oxygen transport in the blood. In contrast, infants require iron for rapid growth and development, making choice B partially correct. Choice C (Old age) and choice D (Male reproductive years) are incorrect as the need for iron typically decreases in old age and remains relatively stable during male reproductive years.
Question 4 of 9
The nurse is caring for a client who’s hypoglycemic. This client will have a blood glucose level:
Correct Answer: A
Rationale: The correct answer is A, below 70mg/dl, for a hypoglycemic client. Hypoglycemia is defined as low blood glucose levels, typically below 70mg/dl. Symptoms of hypoglycemia include confusion, sweating, shakiness, and palpitations. Treating hypoglycemia involves providing the client with a fast-acting source of glucose to raise their blood sugar levels quickly. Choices B, C, and D are incorrect as they indicate normal or elevated blood glucose levels, which are not characteristic of hypoglycemia. It is crucial for the nurse to recognize and promptly address hypoglycemia to prevent potential complications.
Question 5 of 9
A nurse identifies Fatigue as a health problem and nursing diagnosis for a client receiving home care for metastatic cancer. What statement or question would be best to validate this client problem?
Correct Answer: D
Rationale: The correct answer is D because it involves collaboration with the client to validate their experience. It shows respect for the client's perspective and promotes open communication. Choice A is incorrect as it lacks client involvement. Choice B is incorrect as it focuses on the nurse's interpretation rather than the client's experience. Choice C is incorrect as it may come off as accusatory or judgmental, lacking empathy.
Question 6 of 9
A nurse is completing an assessment. Which findings will the nurse report as subjective data? (Select all that apply.)
Correct Answer: C
Rationale: The correct answer is C because subjective data refers to information provided by the patient based on their feelings, perceptions, and experiences. In this case, the patient describing excitement about discharge is subjective data as it reflects the patient's emotional state. The other choices, A, B, and D, are considered objective data because they are observable and measurable by the nurse. The patient's temperature can be measured (A), the wound appearance can be visually assessed (B), and the patient pacing the floor is an observable behavior (D). Therefore, these choices are not subjective data.
Question 7 of 9
For a client in addisonian crisis, it would be very risky for a nurse to administer:
Correct Answer: A
Rationale: The correct answer is A: potassium chloride. In Addisonian crisis, the adrenal glands do not produce enough cortisol and aldosterone. Potassium levels are typically elevated in Addisonian crisis due to decreased aldosterone. Administering potassium chloride can further increase potassium levels, leading to life-threatening cardiac arrhythmias. Hydrocortisone (B) is essential to replace cortisol, normal saline solution (C) helps with volume resuscitation, and fludrocortisone (D) replaces aldosterone. Administering potassium chloride would exacerbate the hyperkalemia in Addisonian crisis.
Question 8 of 9
A nurse is completing an assessment. Which findings will the nurse report as subjective data? (Select all that apply.)
Correct Answer: C
Rationale: Subjective data are information reported by the patient that cannot be observed or measured by others. In this case, choice C is correct because the patient describing excitement about discharge is personal and based on the patient's feelings or perceptions. This is subjective data because it is based on the patient's own experiences and emotions. Choices A and B are incorrect because patient's temperature and wound appearance are objective data that can be measured or observed by the nurse. Choice D is also incorrect as patient pacing the floor is an observable behavior, making it objective data. Therefore, choice C is the correct answer as it represents subjective data in the context of the assessment.
Question 9 of 9
A client on hemodialysis is complaining of muscle weakness and numbness in his legs. His lab results are: Na 136 mEq/L, K 5.9 mEq/L, Cl 100 mEq/L, ca 8.5 mg/dl. Which electrolyte imbalance is the client suffering from?
Correct Answer: A
Rationale: The correct answer is A: Hyperkalemia. In hemodialysis, potassium levels can be elevated due to impaired renal excretion. High potassium can lead to muscle weakness and numbness. The client's K level of 5.9 mEq/L is above the normal range (3.5-5.0 mEq/L), confirming hyperkalemia. Na, Cl, and Ca levels are within normal limits, ruling out hypernatremia, hypochloremia, and hypocalcemia as the client's primary electrolyte imbalance. Monitoring and managing hyperkalemia are crucial to prevent life-threatening complications like cardiac arrhythmias.
