Section 1: Complex Bio-Psycho-Social Assessment and Deteriorating Patient Management
1. A 68-year-old patient with a history of heart failure is admitted with increasing
shortness of breath. On assessment, the nurse auscultates fine crackles at the lung bases and
notes an S3 heart sound. Which haemodynamic parameter BEST reflects this clinical
presentation?
A) A decreased central venous pressure (CVP).
B) An increased pulmonary capillary wedge pressure (PCWP).
C) A decreased systemic vascular resistance (SVR).
D) An increased cardiac index (CI).
correct Answer: B
Rationale: The crackles and S3 gallop are classic signs of left ventricular failure. When the left
ventricle fails, it cannot effectively eject blood, causing pressure to build up backwards into the
,left atrium and pulmonary veins. This elevated pressure is directly measured as an increased
PCWP. A decreased CVP (A) would suggest hypovolaemia. SVR (C) is often increased as a
compensatory mechanism. Cardiac index (D) would be decreased, not increased.
2. A nurse is assessing a patient with septic shock who has a central venous pressure
(CVP) of 2 mmHg, a cardiac output of 8.5 L/min, and a systemic vascular resistance (SVR) of
400 dynes/sec/cm-5. How would the nurse interpret these findings?
A) The patient is in cardiogenic shock and needs inotropic support.
B) The patient is hypovolaemic and requires aggressive fluid resuscitation.
C) The patient has a hyperdynamic state with profound vasodilation, typical of early septic
shock.
D) The patient has a pulmonary embolism causing right heart strain.
correct Answer: C
Rationale: In early (hyperdynamic) septic shock, the release of inflammatory mediators causes
massive vasodilation, which is reflected in the extremely low SVR (normal is 800-1200). The
cardiac output is often initially high as the heart tries to compensate by pumping faster and
harder. The CVP is low due to relative hypovolaemia from fluid shifts and vasodilation. This
combination of low CVP, high CO, and low SVR is a hallmark of septic shock, differentiating it
from cardiogenic (A) or hypovolaemic (B) shock.
3. A patient with a known allergy to penicillin is prescribed co-amoxiclav for a chest
infection. The nurse notes the allergy on the drug chart and withholds the medication. This
action primarily demonstrates which ethical principle?
A) Beneficence
B) Non-maleficence
C) Autonomy
D) Justice
correct Answer: B
Rationale: Non-maleficence is the principle of "do no harm." Withholding a medication to
which a patient has a known, potentially life-threatening allergy is a direct application of this
principle, preventing a foreseeable adverse event. While the other principles are relevant to the
overall care, the primary principle in this specific act is preventing harm.
, 4. A 25-year-old patient with Type 1 diabetes is admitted with diabetic ketoacidosis (DKA).
The nurse is monitoring the patient's potassium level closely. The serum potassium level is 5.5
mEq/L before starting the insulin infusion. What is the correct nursing interpretation?
A) The patient is hyperkalaemic and requires immediate administration of insulin to lower the
potassium.
B) The potassium level is deceptively normal due to the acidosis, and the patient is likely total-
body potassium depleted.
C) The potassium level is high, so the patient will not need any potassium replacement during
treatment.
D) The potassium level is a result of renal failure and the nurse should prepare for dialysis.
correct Answer: B
Rationale: In DKA, the severe metabolic acidosis causes potassium to shift from the intracellular
space to the extracellular space. This gives a falsely elevated or "normal" serum potassium
reading, masking a profound total-body potassium deficit. As insulin and fluids are administered
to treat the DKA, potassium shifts back into the cells, causing a rapid and dangerous drop in
serum potassium. Therefore, potassium replacement is typically started early, even if the initial
level is normal or slightly high, as long as the patient is producing urine.
5. A nurse is using the ABCDE approach to assess a patient who has collapsed. The patient
is unresponsive and has agonal gasps. What is the immediate priority action?
A) Open the airway using a head-tilt, chin-lift manoeuvre.
B) Call for the resuscitation team and a defibrillator.
C) Begin high-quality chest compressions.
D) Attach monitoring equipment to assess the cardiac rhythm.
correct Answer: B
Rationale: In the ABCDE approach, the first step is to assess responsiveness and call for help.
Agonal gasps are a sign of cardiac arrest, not effective breathing. The priority is to activate the
emergency response system and get a defibrillator, as early defibrillation is key to survival in
shockable rhythms. Chest compressions (C) should begin as soon as possible, but the very first
action is to call for help. Opening the airway (A) is part of the BLS algorithm after calling for
help.
, 6. A patient post-thyroidectomy complains of tingling around their mouth and in their
fingertips. The nurse assesses a positive Chvostek's sign. Which serum electrolyte imbalance is
MOST likely?
A) Hyperkalaemia
B) Hyponatraemia
C) Hypocalcaemia
D) Hypomagnesaemia
correct Answer: C
Rationale: Hypocalcaemia is a potential complication of a thyroidectomy due to accidental
removal of or damage to the parathyroid glands, which regulate calcium. The classic signs of
hypocalcaemia are neuromuscular irritability, presenting as tingling (paraesthesia) around the
mouth (circumoral) and in the extremities. Chvostek's sign (facial twitching when tapping over
the facial nerve) and Trousseau's sign (carpal spasm) are indicative of hypocalcaemia.
7. A 55-year-old patient with a history of COPD is admitted with an exacerbation. The
patient is on a Venturi mask at 28% delivering 4L/min. An arterial blood gas (ABG) shows a pH
of 7.32, pCO2 of 65 mmHg, and pO2 of 70 mmHg. The nurse's interpretation of these results
is:
A) The patient is in respiratory alkalosis and the oxygen should be increased.
B) The patient has acute-on-chronic respiratory acidosis, and careful monitoring for signs of CO2
narcosis is required.
C) The patient is fully compensated and no further intervention is needed.
D) The patient is in metabolic acidosis and requires administration of sodium bicarbonate.
correct Answer: B
Rationale: The ABG shows a low pH (acidosis) and a high pCO2 (respiratory cause). This is a
respiratory acidosis. Given the patient's COPD history and the pO2 of 70 mmHg on a low,
controlled concentration of oxygen, this is consistent with an acute exacerbation on a
background of chronic CO2 retention. The priority is careful monitoring. Administering high-flow
oxygen to a CO2 retainer can depress their hypoxic drive, leading to further CO2 retention and
respiratory arrest (CO2 narcosis).
