Nokea
Upon percussion of the midclavicular line from cranial to caudal, you can locate the absolute and relative lung-liver borders. Question: What produces the sound you hear between these two borders?
- A. It is caused by lung tissue
- B. It is caused by liver tissue
- C. It is caused by colon tissue
- D. It is caused by the overlap of lung tissue and liver tissue
Correct Answer: D
Rationale: Lung-liver edge overlap dulls the tap, not pure lung, liver, or colon. Nurses hear this, a chronic border beat.

Which action should the nurse take when caring for a patient who is receiving chemotherapy and complains of problems with concentration?
- A. Teach the patient to rest the brain by avoiding new activities.
- B. Teach that 'chemo-brain' is a short-term effect of chemotherapy.
- C. Report patient symptoms immediately to the health care provider.
- D. Suggest use of a daily planner and encourage adequate rest and sleep.
Correct Answer: D
Rationale: Chemo-brain foggy focus is common; planners and rest help manage, not cure. Resting fully stalls life; it's not always short-term can linger. No emergency it's expected. Nurses in oncology offer this tools and sleep ease the mental muck, supporting function.
A scalp block aims to stop conduction in the following nerves:
- A. Zygomaticotemporal.
- B. Infraorbital.
- C. Greater occipital.
- D. Auriculotemporal.
Correct Answer: C
Rationale: A scalp block is used in awake craniotomy to provide regional anesthesia by blocking sensory nerves innervating the scalp. The greater occipital nerve supplies the posterior scalp, making it a key target. The zygomaticotemporal nerve innervates the temple area, and the auriculotemporal nerve covers the lateral scalp and ear region both are also commonly blocked. The infraorbital nerve supplies the midface, not the scalp, and the trochlear nerve (likely a misnomer for supraorbital or supratrochlear) innervates the forehead, another typical target. However, the greater occipital stands out as essential for posterior coverage, consistently cited in scalp block techniques. The rationale hinges on anatomical innervation: effective scalp anesthesia requires blocking nerves from both trigeminal (V1, V2, V3 branches) and cervical (C2, C3) origins, with the greater occipital being a primary cervical contributor, ensuring comprehensive pain control during surgery.
Erysipelas
- A. responds to erythromycin
- B. is caused strep pneumoniae
- C. results from microorganism exotoxin production
- D. typically occurs on the neck
Correct Answer: A
Rationale: Erysipelas erythro clears strep pyogenes, not pneumo, toxins, neck-only, or TEN's peel. Nurses dose this chronic red edge.
The challenges faced in insulin therapy includes the following EXCEPT:
- A. Needle phobia
- B. Competence - Diabetes numeracy
- C. Dexterity
- D. All burden
Correct Answer: D
Rationale: Insulin hurdles fear, math, shaky hands, life jolts; all burden' isn't a thing, just a mash-up. Nurses tackle these chronic snags, not vague catch-alls.
How do oxygen radicals react with different molecules?
- A. By accepting an electron
- B. By donating an electron
- C. By accepting a proton
- D. By donating a proton
Correct Answer: A
Rationale: Oxygen radicals grab electrons unpaired, they steal, wrecking cells, not giving or juggling protons. A chronic chaos starter nurses know this chemistry bite.
