Nokea
Which agent is the usually choice for moderate to severe travelers diarrhea?
- A. metronidazole
- B. doxycycline
- C. norfloxacin
- D. penicillin
Correct Answer: C
Rationale: Norfloxacin fluoroquinolone zaps travelers' E. coli, not metro, doxy, pen, or cotrim's fade. Nurses pick this chronic gut punch.

The body has several mechanisms to increase the blood glucose level in case of hypoglycaemia. Question: Which of the following options best describes the role of glucagon and adrenaline in hypoglycaemia?
- A. Glucagon and adrenaline stimulate glycogenolysis in the liver
- B. Glucagon and adrenaline inhibit the insulin-stimulated glucose uptake in the muscles
- C. Glucagon stimulates glycogen synthase and adrenaline stimulates glycogenolysis in the liver
- D. Glucagon and adrenaline stimulate glycogen synthase en adrenaline stimulates glycogenolysis in the muscles
Correct Answer: A
Rationale: Hypo hits glucagon and adrenaline rip glycogen apart in liver, sugar surges. No muscle block, no synthase flip straight breakdown's the play nurses watch this, a chronic rescue duo.
The nurse is caring for a patient with an advanced stage of breast cancer and the patient has recently learned that her cancer has metastasized. The nurse enters the room and finds the patient struggling to breathe and the nurse's rapid assessment reveals that the patient's jugular veins are distended. The nurse should suspect the development of what oncologic emergency?
- A. Increased intracranial pressure
- B. Superior vena cava syndrome (SVCS)
- C. Spinal cord compression
- D. Metastatic tumor of the neck
Correct Answer: B
Rationale: Dyspnea plus distended jugulars scream SVCS breast cancer's mets can squeeze the vena cava, blocking venous return from the head and chest. It's an oncology emergency, fast-tracking to edema and airway issues if unchecked. Intracranial pressure needs brain involvement less likely here. Spinal compression hits legs and bladder, not breathing. Neck tumors might press locally, but SVCS fits this picture. Nurses jump on this, pushing for steroids or stenting, knowing seconds count.
While performing an admission assessment for a client, the nurse notes that the client has varicose veins with ulcerations and lower extremity edema with a report of a feeling of heaviness. Which of the following nursing diagnoses should the nurse identify as the priority in the client's care?
- A. Ineffective peripheral tissue perfusion
- B. Alteration in body image
- C. Impaired skin integrity
- D. Alteration in activity tolerance
Correct Answer: C
Rationale: Varicose veins with ulcerations, edema, and heaviness scream venous stasis impaired skin integrity tops the list as open sores risk infection, a pressing threat needing immediate wound care. Ineffective perfusion drives the issue, but skin breakdown's acuity trumps. Body image matters emotionally, less urgently. Activity tolerance lags behind active complications. Nurses prioritize skin integrity, addressing ulcers' vulnerability, a direct care focus to halt deterioration in this chronic venous picture, aligning with safety and healing goals.
Which of the following is not complication associated with NAFLD?
- A. Ischemic heart disease
- B. Cerebrovascular accident
- C. Colon cancer
- D. All of the above
Correct Answer: D
Rationale: NAFLD heart, stroke, colon, liver cancer all link; no outlier. Nurses track this chronic risk chain.
A 75-year-old female presented to the emergency department with shortness of breath. The client's daughter is at the bedside and shares that the client has a history of heart failure. The nurse places the client on the cardiac monitor and finds that the client is in atrial fibrillation at a rate of 180 beats per minute. Which is a likely finding?
- A. Bounding pulses
- B. Lethargy
- C. Hypotension
- D. Edema
Correct Answer: C
Rationale: Atrial fibrillation at 180 beats/minute in heart failure loses atrial kick, slashing output hypotension follows as rapid, erratic beats fail to fill ventricles, a likely finding with this tachycardic chaos. Bounding pulses need strong ejection, not here. Lethargy or edema might emerge, but BP drop's immediate, tied to poor perfusion. Nurses expect this, anticipating rate control or fluids, a critical catch in this acute decompensation.
