Which of the following can cause coup-contrecoup injuries?
- A. Rotational forces
- B. Deformation forces
- C. Deceleration forces
- D. Acceleration forces
Correct Answer: C
Rationale: Deceleration forces occur when the head is moving and abruptly comes to a stop, such as in a car crash. This sudden deceleration can cause the brain to hit against the skull, resulting in coup-contrecoup injuries. In a coup-contrecoup injury, the brain is damaged on opposite sides due to the initial impact and the rebound effect inside the skull. Rotational forces usually result in diffuse axonal injuries rather than coup-contrecoup injuries. Deformation forces can cause focal brain injuries but not coup-contrecoup injuries. Acceleration forces typically lead to diffuse brain injuries, not coup-contrecoup injuries. Therefore, the correct answer is deceleration forces.

When caring for an asthmatic patient with an early-phase reaction, which of the following is indicative of an early-phase reaction?
- A. Rapid bronchospasms
- B. Inflammatory epithelial lesions
- C. Increased secretions
- D. Increased mucosal edema
Correct Answer: A
Rationale: Rapid bronchospasms are a symptom of an early-phase reaction in an asthmatic patient. During the early phase, bronchospasms occur due to immediate hypersensitivity reactions. Inflammatory epithelial lesions, increased secretions, and increased mucosal edema are typically seen in late-phase reactions as part of the inflammatory response that occurs later. Therefore, rapid bronchospasms are most indicative of an early-phase reaction.
In which part of the plan of care should a nurse record the item 'Encourage patient to attend one psychoeducational group daily'?
- A. Assessment
- B. Analysis
- C. Planning
- D. Implementation
Correct Answer: D
Rationale: The correct answer is 'Implementation.' In the nursing process, implementation involves carrying out the planned interventions to meet the patient's goals. Encouraging the patient to attend a psychoeducational group daily is an intervention aimed at building social skills. Assessment (choice A) is the phase where data about the patient's condition is collected. Analysis (choice B) involves interpreting the gathered data. Planning (choice C) is where the nurse decides on the interventions to address the patient's needs. Therefore, in this scenario, recording the item 'Encourage patient to attend one psychoeducational group daily' would be part of the implementation phase.
Which of the following glands found in the skin secretes a liquid called Sebum?
- A. Apocrine Glands
- B. Sebaceous Glands
- C. Lacrimal Glands
- D. Sweat Glands
Correct Answer: B
Rationale: Sebum is a liquid secreted by glands in the skin known as sebaceous glands. Sebum's primary function is to lubricate the skin and help maintain its integrity. Apocrine glands secrete a different type of sweat that is odorless but can develop an odor when combined with bacteria on the skin. Lacrimal glands produce tears to keep the eyes moist, and sweat glands secrete sweat to regulate body temperature through evaporation. Therefore, the correct answer is Sebaceous Glands because they specifically secrete sebum, distinguishing them from the other gland types mentioned.
During an intake screening for a patient with hypertension who has been taking ramipril for 4 weeks, which statement made by the patient would be most important for the nurse to pass on to the physician?
- A. I get dizzy when I get out of bed.''
- B. I'm urinating much more than I used to.''
- C. I've been running on the treadmill for 10 minutes each day.''
- D. I can't get rid of this cough.''
Correct Answer: D
Rationale: The correct answer is ''I can't get rid of this cough.'' Ramipril, an ACE inhibitor, commonly causes a persistent, dry cough as an adverse effect. This symptom can be indicative of bradykinin accumulation caused by ACE inhibitors. It is important for the nurse to inform the physician about this side effect so that a medication change to another class of antihypertensives, such as an ARB, may be considered. Choices A, B, and C are not directly related to the common adverse effects of ramipril and are not as concerning for a patient on this medication.
The healthcare provider calculates the IV flow rate for a patient receiving lactated Ringer's solution. The patient needs to receive 2000mL of Lactated Ringer's over 36 hours. The IV infusion set has a drop factor of 15 drops per milliliter. How many drops per minute should the healthcare provider set the IV to deliver?
- A. 8
- B. 10
- C. 14
- D. 18
Correct Answer: C
Rationale: To determine the drops per minute, we use the formula Drops Per Minute = (Milliliters x Drop Factor) / Time in Minutes. In this case, Drops Per Minute = (2000mL x 15 drops/mL) / (36 hours x 60 minutes/hour) = 30000 / 2160 = 13.89 (approximately 14). Therefore, the correct answer is 14 drops per minute. Choice A (8), Choice B (10), and Choice D (18) are incorrect as they do not correctly calculate the drops per minute based on the given information.
