In staging pressure ulcers (bedsores), an area of intact skin with non-blanchable erythema over a bony prominence corresponds to:
💡
Step-by-Step Explanation & Concept Rationale

What is the standard minimum temperature and holding time required for moist-heat sterilization inside an autoclave operating at 15 psi pressure?
💡
Step-by-Step Explanation & Concept Rationale
Autoclaving utilizes saturated pressurized steam at 121°C (250°F) under 15 psi (103 kPa) for at least 15-20 minutes to kill all vegetative microorganisms and bacterial endospores.

To prevent urinary tract infections in a patient with an indwelling Foley catheter, the drainage bag should always be positioned:
💡
Step-by-Step Explanation & Concept Rationale
Keeping the drainage bag below the level of the bladder prevents retrograde backflow of contaminated urine into the bladder, which is the primary cause of CAUTI.

When administering an intramuscular (IM) injection to an adult, what is the correct angle of needle insertion into the muscle?
💡
Step-by-Step Explanation & Concept Rationale

Which of the following describes the correct technique for sterile donning of gloves?
💡
Step-by-Step Explanation & Concept Rationale
When donning sterile gloves, the un-gloved hand touches only the turned-down inner cuff (which will be in contact with the skin), preserving the outer glove sterility.

Which of the following is an example of an airborne isolation precaution requiring an N95 respirator mask and negative-pressure isolation room?
💡
Step-by-Step Explanation & Concept Rationale

The normal oral body temperature range for an adult in degrees Celsius is approximately:
💡
Step-by-Step Explanation & Concept Rationale
Normal adult body temperature typically fluctuates between 36.5°C and 37.5°C (97.7°F to 99.5°F).

Difficulty: Medium
(1 Mark)
A patient with a water-seal chest drainage system has continuous vigorous bubbling in the water-seal chamber. What does this finding indicate to the nurse?
💡
Step-by-Step Explanation & Concept Rationale
Intermittent tidaling/bubbling with coughing is normal, but continuous bubbling in the water-seal chamber indicates a leak in the drainage apparatus or persistent pneumothorax.

(1 Mark)
During a blood transfusion, the patient complains of chills, back pain, fever, and shortness of breath 10 minutes into the infusion. What is the immediate priority nursing action?
💡
Step-by-Step Explanation & Concept Rationale
At the first sign of an acute hemolytic or severe transfusion reaction, the transfusion must be stopped immediately to minimize foreign antigen exposure while maintaining IV access with fresh tubing and 0.9% saline.

Which clinical sign elicited by tapping the facial nerve anterior to the earlobe produces facial twitching, indicating hypocalcemia in a post-thyroidectomy patient?
💡
Step-by-Step Explanation & Concept Rationale
Chvostek's sign is unprovoked or percussion-induced twitching of the circumoral and facial muscles caused by neuromuscular hyperexcitability from hypocalcemia.

The Glasgow Coma Scale (GCS) evaluates neurological responsiveness across which three behavioral domains?
💡
Step-by-Step Explanation & Concept Rationale
The Glasgow Coma Scale assesses Eye Opening (1-4), Verbal Response (1-5), and Motor Response (1-6) for a score ranging from 3 (deep coma) to 15 (fully alert).

(1 Mark)
In a patient with deep vein thrombosis (DVT) in the left calf, which nursing intervention is STRICTLY contraindicated?
💡
Step-by-Step Explanation & Concept Rationale
Vigorously massaging or rubbing the affected extremity can dislodge the thrombus, precipitating potentially fatal pulmonary embolism.
Q. 16
Nursing
Difficulty: Easy
(1 Mark)
What is the primary post-operative nursing rationale for encouraging early ambulation and deep breathing exercises following major abdominal surgery?
💡
Step-by-Step Explanation & Concept Rationale
Early ambulation promotes venous return to prevent DVT and stimulates diaphragmatic movement to reverse alveolar collapse (atelectasis) and prevent hypostatic pneumonia.
Q. 17
Nursing
Difficulty: Easy
(1 Mark)
Which of the following is the most characteristic early clinical indicator of developing hypovolemic shock?
💡
Step-by-Step Explanation & Concept Rationale
Compensatory tachycardia and peripheral vasoconstriction (cool, clammy skin) occur early in hypovolemia as sympathetic activation attempts to maintain cardiac output before blood pressure falls.

Nursing
Difficulty: Medium
(1 Mark)
For an unconscious patient with a tracheostomy, what is the maximum recommended duration for a single endotracheal suctioning pass to prevent severe hypoxia?
💡
Step-by-Step Explanation & Concept Rationale
Suction passes should not exceed 10 to 15 seconds to prevent suction-induced hypoxia, bradycardia, and mucosal trauma; hyperoxygenation before and after is essential.

In a diabetic patient who becomes confused, diaphoresis, shaky, and tachycardia with a capillary blood glucose of 45 mg/dL, what is the immediate nursing intervention if conscious?
💡
Step-by-Step Explanation & Concept Rationale
The 'Rule of 15' dictates giving 15-20 g of simple fast-acting carbohydrate (half cup fruit juice or 3-4 glucose tablets) for mild-to-moderate hypoglycemia, rechecking glucose after 15 minutes.
Q. 20

Difficulty: Medium
(1 Mark)
Which clinical observation is the earliest and most sensitive sign of increasing intracranial pressure (ICP)?
💡
Step-by-Step Explanation & Concept Rationale
Altered level of consciousness is the most sensitive early indicator of rising ICP; pupillary changes and Cushing's triad are late signs indicating imminent brainstem herniation.

An infant at 1 minute of life has a heart rate of 110 bpm, good vigorous cry, active motion of all extremities, grimaces to suctioning, but has pink body with blue extremities (acrocyanosis). What is the APGAR score?
💡
Step-by-Step Explanation & Concept Rationale
Heart rate >100 (2), Good cry/respiration (2), Active motion/muscle tone (2), Grimace/reflex (2), Acrocyanosis/color (1) = Total APGAR score of 9.

The first stage of labor is defined as extending from the onset of true labor contractions until:
💡
Step-by-Step Explanation & Concept Rationale
The first stage of labor begins with regular uterine contractions and concludes with complete cervical dilatation (10 cm). The second stage is delivery of the infant, and the third stage is delivery of the placenta.

When caring for a newborn receiving phototherapy for physiological neonatal jaundice, which essential nursing precautions must be maintained?
💡
Step-by-Step Explanation & Concept Rationale
Eye shields protect retinas from photochemical damage; genitalia are covered, and frequent breastfeeding is promoted to prevent dehydration and accelerate bilirubin excretion.

At what age should exclusive breastfeeding ideally be supplemented with timely, nutritionally adequate complementary feeding (weaning)?
💡
Step-by-Step Explanation & Concept Rationale
WHO and UNICEF recommend exclusive breastfeeding for the first 6 months of life, followed by introduction of safe and nutritionally adequate complementary foods while continuing breastfeeding up to 2 years.
Q. 25

In a post-term pregnant patient receiving oxytocin (Pitocin) infusion for labor augmentation, what pattern of uterine contractions signifies hyperstimulation requiring immediate stoppage of oxytocin?
💡
Step-by-Step Explanation & Concept Rationale
Uterine tachysystole (>5 contractions in 10 minutes or duration >90 seconds) compromises uteroplacental perfusion, causing fetal hypoxia; oxytocin must be discontinued immediately.
