Which of the following appropriately describes diastolic dysfunction?
- A. The rate of filling of the ventricles during diastole is slowed
- B. The left ventricle is dilated
- C. The preload (end ventricular diastolic volume) is increased
- D. The left ventricular ejection fraction is decreased
Correct Answer: A
Rationale: Diastolic dysfunction stiffens ventricles slowed filling in diastole nails it, as relaxation flops, hiking pressure. Dilated LV or high preload fits systolic; low EF's not here preserved in HFpEF. Dyssynchrony's another beast. Clinicians peg this slow fill, a chronic heart kink distinct from pump fail.

During his internship at a general practice, a medical student is asked to check the blood glucose level in a 50-year-old patient with type 2 diabetes. The measurement is performed at a random moment and the carbohydrate intake has not been standardised before the measurement is taken. The result of the measurement is shown below. The general practitioner (GP) asks the student to report the result using standard medical terminology. Question: Which diagnosis is most consistent with the findings provided above?
- A. Hyperglycaemia
- B. Hypoglycaemia
- C. Hyperglycaemia with hyperosmolar state
- D. Normoglycaemia (euglycaemia)
Correct Answer: A
Rationale: Random high glucose in type 2 hyperglycaemia, no hypo, osmolar crash, or norm. Nurses call this, a chronic sugar spike.
You are caring for a patient with esophageal cancer. Which task could be delegated to the nursing assistant?
- A. Assist the patient with oral hygiene
- B. Observe the patient's response to feedings
- C. Facilitate expression of grief or anxiety
- D. Initiate daily weights
Correct Answer: A
Rationale: Delegating tasks in nursing hinges on scope of practice. Assisting with oral hygiene is a basic care activity nursing assistants are trained to perform, supporting hygiene needs in esophageal cancer patients who may struggle with swallowing. Observing responses to feedings requires clinical judgment to assess tolerance or complications, a nurse's responsibility. Facilitating emotional expression involves therapeutic communication skills beyond an assistant's training, critical for addressing cancer-related distress. Initiating daily weights implies deciding when to start, requiring understanding of fluid status assistants can weigh patients but not initiate the process independently. Oral hygiene delegation optimizes care efficiency, aligns with assistants' capabilities, and frees nurses for higher-level assessments, ensuring safe, effective management of this patient's complex needs.
A client states that their legs have pain with walking that decreases with rest. The nurse observes absence of hair on the client's lower extremities and the client has a thread, weakened posterior tibial pulse. What would be the best position to have the client's legs?
- A. Elevated above the heart
- B. Slightly bent with three pillows under the knees
- C. Crossed at the knee
- D. Hanging down
Correct Answer: D
Rationale: PAD's claudication pain with walking, eased by rest plus hairless legs and weak pulses cry ischemia. Hanging legs down boosts gravity-fed flow, easing pain, the best position here. Elevation cuts supply, worsening it. Bending or crossing risks pressure. Nurses dangle limbs, enhancing perfusion, a practical fix in this arterial crunch.
How do you treat secondary syphilis?
- A. oral penicillin
- B. i.m. penicillin
- C. i.v. penicillin
- D. erythromycin
Correct Answer: B
Rationale: Secondary syphilis IM penicillin blasts treponemes, not oral, IV, or erythro sidesteps. Nurses shoot this chronic cure.
The nurse administers an IV vesicant chemotherapeutic agent to a patient. Which action is most important for the nurse to take?
- A. Infuse the medication over a short period of time.
- B. Stop the infusion if swelling is observed at the site.
- C. Administer the chemotherapy through a small-bore catheter.
- D. Hold the medication unless a central venous line is available.
Correct Answer: B
Rationale: Vesicants (e.g., vincristine) burn tissue if they leak swelling at the site yells extravasation; stopping the IV stat limits necrosis. Fast infusion ups vein stress; small-bore risks rupture running IVs dilute it. Central lines are gold but not mandatory. Nurses in oncology prioritize this catching leaks early saves skin, a critical save in chemo land.
