1. When should the client administer the inhaler-delivered medication to demonstrate correct use of the inhaler?
- A. Immediately after exhalation.
- B. During the inhalation.
- C. At the end of three inhalations.
- D. Immediately after inhalation.
Correct answer: B
Rationale: The correct answer is B: 'During the inhalation.' Administering the medication while inhaling ensures proper delivery to the lungs. Inhaling the medication allows it to reach the lungs effectively for optimal therapeutic benefit. Choices A, C, and D are incorrect because administering the medication after exhalation or at the end of inhalations may result in improper drug delivery and reduced therapeutic effects.
2. In a long term rehabilitation care unit a client with spinal cord injury complains of a pounding headache. The client is sitting in a wheelchair watching television in the assigned room. Further assessment by the nurse reveals excessive sweating, a splotchy rash, pilomotor erection, facial flushing, congested nasal passages and a heart rate of 50. The nurse should do which action next?
- A. Take the client's respirations, blood pressure (BP), temperature and then pupillary responses
- B. Place the client into the bed and administer the ordered PRN analgesic
- C. Check the client for bladder distention and the client's urinary catheter for kinks
- D. Turn the television off and then assist client to use relaxation techniques
Correct answer: C
Rationale: These symptoms suggest autonomic dysreflexia, often triggered by bladder distention.
3. A client has left lower atelectasis. In which of the following positions should the nurse place the client for postural drainage?
- A. Supine and low Fowler's position
- B. Right lateral in Trendelenburg position
- C. Side lying with the right side of the chest elevated
- D. Prone with pillows under the extremities
Correct answer: B
Rationale: Postural drainage is a technique used to help remove secretions from specific lung segments. For left lower atelectasis, placing the client in the right lateral Trendelenburg position is most effective. This position helps target the affected area, using gravity to assist in drainage. Placing the client in a supine or low Fowler's position (Choice A) may not effectively target the affected area. Side lying with the right side of the chest elevated (Choice C) would not utilize gravity for optimal drainage. Placing the client prone with pillows under the extremities (Choice D) is not ideal for postural drainage of the left lower lobe.
4. Insulin forces which of the following electrolytes out of the plasma and into the cells?
- A. Calcium
- B. Magnesium
- C. Phosphorus
- D. Potassium
Correct answer: D
Rationale: Insulin forces potassium out of the plasma and into the cells, which can cause hypokalemia. This is because insulin enhances the activity of the sodium-potassium pump in cell membranes, promoting the movement of potassium from the extracellular fluid into the cells. Choices A, B, and C are incorrect as insulin does not directly influence the movement of calcium, magnesium, or phosphorus in the same manner as it does with potassium.
5. An individual’s phenotype reflects both genetic and environmental influences.
- A. phenotype
- B. chromosome
- C. allele
- D. genotype
Correct answer: A
Rationale: The correct answer is A: phenotype. A phenotype is the observable characteristics of an individual, which result from the interaction of their genotype with the environment. This interaction between genetics and the environment determines how genes are expressed and how traits are manifested in an individual. Choices B, C, and D are incorrect because chromosomes, alleles, and genotypes are components of an individual's genetic makeup, but they do not directly reflect the observable traits influenced by both genetics and the environment.
