A healthcare professional is assessing a patient in the rehab unit during shift change. The patient has sustained a TBI 3 weeks ago. Which of the following is the most distinguishing characteristic of a neurological disturbance?
- A. LOC (level of consciousness)
- B. Short-term memory
- C. Babinski sign
- D. Clonus sign
Correct Answer: A
Rationale: Level of consciousness (LOC) is the most crucial indicator of impaired neurological function. Changes in LOC can signify various neurological conditions, including traumatic brain injury. Short-term memory, while important, is not the most distinguishing characteristic of neurological disturbances. Babinski and Clonus signs are specific neurological tests that can provide information about upper motor neuron lesions but are not as generalizable as changes in LOC for assessing overall neurological status.

A patient has recently been prescribed Norvasc. Which of the following side effects should the patient specifically watch out for?
- A. Hypotension and Angina
- B. Hypertension
- C. Lower extremity edema
- D. Peripheral sensory loss and SOB
Correct Answer: A
Rationale: The correct answer is 'Hypotension and Angina.' Norvasc is a medication known to cause hypotension (low blood pressure) and angina (chest pain) as side effects. These side effects are important for the patient to watch out for as they can indicate potential issues related to the medication. Choice B ('Hypertension') is incorrect as Norvasc is actually used to treat hypertension, not cause it. Choice C ('Lower extremity edema') is not a common side effect of Norvasc. Choice D ('Peripheral sensory loss and SOB') is not typically associated with Norvasc's side effects.
A healthcare professional is reviewing a patient's serum glucose levels. Which of the following scenarios would indicate abnormal serum glucose values for a 30-year-old male?
- A. 70 mg/dL
- B. 55 mg/dL
- C. 110 mg/dL
- D. 100 mg/dL
Correct Answer: B
Rationale: The correct answer is 55 mg/dL. The standard range for serum glucose levels is typically 60-115 mg/dL. A serum glucose level of 55 mg/dL falls below this range, indicating hypoglycemia. Options A, C, and D are within the standard range for serum glucose levels and would not be considered abnormal for a 30-year-old male.
Jane Love, a 35-year-old gravida III para II at 23 weeks gestation, is seen in the Emergency Department with painless, bright red vaginal bleeding. Jane reports that she has been feeling tired and has noticed ankle swelling in the evening. Laboratory tests reveal a hemoglobin level of 11.5 g/dL. After evaluating the situation, the nurse determines that Jane is at risk for placenta previa, based on which of the following data?
- A. anemia
- B. edema
- C. painless vaginal bleeding
- D. fatigue
Correct Answer: C
Rationale: Placenta previa is a disorder where the placenta implants in the lower uterine segment, causing painless bleeding in the third trimester of pregnancy. The bleeding results from tearing of the placental villi from the uterine wall as the lower uterine segment contracts and dilates. It can be slight or profuse and can include bright red, painless bleeding. While anemia (choice A) may be a consequence of chronic bleeding from placenta previa, it is not a direct indicator. Edema (choice B) and fatigue (choice D) are nonspecific symptoms that can occur in pregnancy but are not specific to placenta previa.
Laboratory tests reveal the following electrolyte values for Mr. Smith: Na 135 mEq/L, Ca 8.5 mg/dL, Cl 102 mEq/L, and K 2.0 mEq/L. Which of the following values should the nurse report to the physician because of its potential risk to the client?
- A. Ca
- B. K
- C. Na
- D. Cl
Correct Answer: B
Rationale: The correct answer is 'K.' Normal serum potassium levels range between 3.5 and 5.5 mEq/L. Mr. Smith's potassium level of 2.0 mEq/L is significantly below the normal range, indicating hypokalemia, which can lead to serious risks such as cardiac arrhythmias. The levels of sodium (Na), calcium (Ca), and chloride (Cl) are within normal ranges, so they do not pose an immediate risk to the client's health. Therefore, the nurse should report the low potassium level to the physician for prompt intervention.
When assessing a client with early impairment of oxygen perfusion, such as a pulmonary embolus, the nurse should expect to find restlessness and which of the following symptoms?
- A. cool, clammy skin
- B. bradycardia
- C. tachycardia
- D. eupnea
Correct Answer: C
Rationale: When a client has early impairment of oxygen perfusion, such as in a pulmonary embolus, the nurse should expect to find restlessness, diaphoresis, tachycardia, and cool skin. Tachycardia is a compensatory mechanism to increase oxygen delivery to tissues. Cool, clammy skin (choice A) is more indicative of impaired oxygen perfusion compared to warm, dry skin. Bradycardia (choice B) is less likely to occur in the early stages and is more common in severe cases. Eupnea (choice D) refers to normal respirations in rate and depth, which may not be altered in early impairment of oxygen perfusion.
