With severe diarrhea, electrolytes as well as fluids are lost. What electrolyte imbalance is indicated in Ms. CC’s decreased muscle tone and deep tendon reflexes?
- A. Hypernatremia
- B. Hyperchoremia
- C. Hypokalemia
- D. Hypocalcemia
Correct Answer: D
Rationale: The correct answer is D: Hypocalcemia. Severe diarrhea can lead to electrolyte imbalances, including low calcium levels. Decreased muscle tone and deep tendon reflexes are classic signs of hypocalcemia. Calcium is essential for proper muscle function and nerve transmission. Hypernatremia (A) is high sodium levels, not related to decreased muscle tone. Hyperchloremia (B) is high chloride levels, not associated with muscle tone changes. Hypokalemia (C) is low potassium levels, which can cause muscle weakness but not specifically decreased muscle tone and deep tendon reflexes like hypocalcemia.

An adult has a central venous line. Which of the following should the nurse include in the plan of care?
- A. Complete blood count and electrolytes
- B. Regular chest x rays to ensure proper placement of the central line
- C. Continuous infusion of the solution at a keep vein open rate
- D. Any signs of infection, air embolus, and leakage or puncture
Correct Answer: D
Rationale: The correct answer is D because monitoring for signs of infection, air embolus, and leakage/puncture are crucial in caring for a patient with a central venous line to prevent serious complications. Infections can lead to sepsis, air embolus can cause respiratory distress, and leakage/puncture can result in hemorrhage or damage to surrounding tissues.
A: While a complete blood count and electrolytes may be important for monitoring the patient's overall health, they are not specific to the central venous line care.
B: Regular chest x-rays are not necessary unless there are specific indications of line malposition or complications.
C: Continuous infusion at a keep-vein-open rate is a standard practice but does not address the critical aspects of central line care mentioned in option D.
Therefore, monitoring for signs of infection, air embolus, and leakage/puncture is the most essential component of the plan of care for a patient with a central venous line.
Wilma was shocked to see that the Tracheostomy was dislodged. Both the inner and outer cannulas was removed and left hanging on James’ neck. What are the 2 equipment’s at james’ bedside that could help Wilma deal with this situation?
- A. New set of tracheostomy tubes and Oxygen tank
- B. Theophylline and Epinephrine
- C. Obturator and Kelly clamp
- D. Sterile saline dressing
Correct Answer: A
Rationale: The correct answer is A: New set of tracheostomy tubes and Oxygen tank.
Rationale:
1. New set of tracheostomy tubes: Essential for reinserting the cannulas to secure the airway.
2. Oxygen tank: To ensure James has a stable oxygen supply while the tracheostomy tubes are being reinserted.
Summary of incorrect choices:
B: Theophylline and Epinephrine - These medications are not directly related to managing a dislodged tracheostomy.
C: Obturator and Kelly clamp - While these are useful tools for tracheostomy care, they are not the immediate equipment needed in this emergency situation.
D: Sterile saline dressing - This is not relevant for a dislodged tracheostomy; the priority is securing the airway.
Cancer is the second major cause of death in this country. What is the first step toward effective cancer control?
- A. Increasing governmental control of potential carcinogens
- B. Changing habits and customs that predispose the individual to cancer
- C. Conducting more mass screening programs
- D. Educating public and professional people about cancer
Correct Answer: B
Rationale: The correct answer is B because changing habits and customs that predispose the individual to cancer is crucial in preventing cancer. This includes lifestyle changes such as quitting smoking, maintaining a healthy diet, exercising regularly, and avoiding excessive sun exposure. By modifying behaviors that increase cancer risk, individuals can significantly reduce their chances of developing cancer.
A: Increasing governmental control of potential carcinogens is not the first step towards effective cancer control as individual behaviors have a more direct impact on cancer risk.
C: Conducting more mass screening programs is important but not the first step as prevention through lifestyle changes takes priority.
D: Educating the public and professionals about cancer is essential but changing habits is the initial crucial step in effective cancer control.
The following. items are transported in blood plasma, EXCEPT:
- A. Oxygen
- B. Carbon dioxide
- C. Nutrients
- D. Hormones
Correct Answer: A
Rationale: The correct answer is A: Oxygen. Oxygen is primarily transported in the blood bound to hemoglobin within red blood cells, not dissolved in plasma. Carbon dioxide is transported in plasma. Nutrients and hormones are also transported in plasma. Therefore, choice A is incorrect as oxygen is not primarily transported in plasma.
A client with diabetes mellitus has a prescription for 5 U-100 regular insulin and 25 U of U-100 isophane insulin suspension (NPH) to be taken before breakfast. At about 4:30 p.m., the client experiences headache, sweating, tremor, pallor, and nervousness. What is the most probable cause of these signs and symptoms?
- A. Hyperglycemia
- B. Hyperuricemia
- C. Hypoglycemia
- D. Hypochondria
Correct Answer: C
Rationale: The correct answer is C: Hypoglycemia. At 4:30 p.m., after taking the morning insulin, the client's blood sugar may have dropped too low, leading to symptoms like headache, sweating, tremor, pallor, and nervousness. Regular insulin and NPH insulin peak at different times, causing a potential mismatch in insulin action, leading to hypoglycemia. Hyperglycemia (A) would present with different symptoms like increased thirst and urination. Hyperuricemia (B) is an excess of uric acid in the blood and does not typically present with these symptoms. Hypochondria (D) is a psychological condition and not related to the client's physical symptoms.
