1. Which of the following signs or symptoms indicates a possible nutritional deficiency?
- A. Subcutaneous fat at the waist and abdomen
- B. Presence of papillae on the surface of the tongue
- C. Straight arms and legs
- D. Pale conjunctiva
Correct answer: D
Rationale: A client with poor nutritional intake may have pale mucous membranes surrounding the eye, or the conjunctiva. This area should normally be pink, indicating good circulation and a lack of irritation or dryness. Improper nutrition can manifest as numerous signs in the body, including bowed legs, pale mucous membranes, a smooth or beefy tongue, and poor muscle tone. Subcutaneous fat at the waist and abdomen is not a sign of nutritional deficiency but rather of excess fat deposition. The presence of papillae on the surface of the tongue is normal and not indicative of a nutritional deficiency. Straight arms and legs are also typical anatomical features and not specifically related to nutritional deficiencies.
2. When printing out an EKG, a nurse notices that the QRS complexes are extremely small. What should be the next step?
- A. Alert the physician immediately as this is a sign of impending cardiac arrest.
- B. Check to see that all leads are attached and rerun the EKG.
- C. Increase the sensitivity control to 20 mm deflection.
- D. Decrease the run speed to 50.
Correct answer: C
Rationale: Increasing the sensitivity control to 20 mm deflection will double the sensitivity, allowing for better observation of the small QRS complexes. This step is crucial in obtaining a clearer EKG reading. Choice A is incorrect because small QRS complexes do not necessarily indicate impending cardiac arrest; it's more likely a technical issue. Choice B is not the first step to take when small QRS complexes are observed; it's important to adjust the settings first. Choice D is incorrect because decreasing the run speed to 50 is not the appropriate action for this situation; adjusting the sensitivity control is more relevant to improve the visualization of the complexes.
3. Where is the Loop of Henle located in the body?
- A. Liver
- B. Kidney
- C. Heart
- D. Ear
Correct answer: B
Rationale: The Loop of Henle is a crucial structure found in the kidneys. It plays a vital role in the concentration of urine by creating a concentration gradient in the renal medulla. Choices A, C, and D are incorrect because the Loop of Henle is not located in the liver, heart, or ear. Understanding the anatomical location of the Loop of Henle is essential in comprehending renal physiology and the mechanism of action of diuretic medications.
4. An Asian-American woman is experiencing diarrhea, which is believed to be "cold"? or "yin."? What should the nurse recognize that the woman may likely try to treat it?
- A. Foods that are "hot"? or "yang"?
- B. Readings and Eastern medicine meditations
- C. High doses of medicines believed to be "cold"?
- D. No treatment because diarrhea is an expected part of life.
Correct answer: A
Rationale: In this scenario, the Asian-American woman is believed to be experiencing diarrhea due to a "cold"? or "yin"? imbalance. According to the yin/yang theory, yang represents heat and yin represents cold. Therefore, to balance the cold nature of the diarrhea, the woman may try to treat it by consuming foods that are considered "hot"? or "yang"?. This aligns with the concept that cold foods are eaten with a hot illness, and hot foods are eaten with a cold illness. Choices B, C, and D do not align with the yin/yang theory and are not relevant to addressing the imbalance associated with the cold nature of the diarrhea.
5. A home health nurse is preparing to visit her next client, whom she has never visited before. Which of the following actions indicates the nurse is upholding safety precautions?
- A. Send a text to the client to confirm the location of the house
- B. Leave her purse and valuables on the seat in the car and lock the doors
- C. Ask the client to keep an extra set of keys in case the car is locked
- D. Keep the car windows rolled up when in an unfamiliar environment
Correct answer: D
Rationale: The correct answer is to keep the car windows rolled up when in an unfamiliar environment. This action helps uphold safety precautions for the home health nurse. When visiting a new client in an unfamiliar area, it is essential to ensure personal safety. Keeping the car windows rolled up can prevent potential intruders or unwanted individuals from gaining access to the nurse while in the vehicle. This precaution is important for personal safety and security. Choice A, sending a text to the client to confirm the location of the house, is not directly related to the nurse's safety during the visit. While communication with the client is important, it does not directly address the nurse's safety. Choice B, leaving her purse and valuables on the seat in the car, poses a security risk. It is not advisable to leave valuables visible in the car, as it may attract thieves and compromise the nurse's safety. Choice C, asking the client to keep an extra set of keys, is more related to accessibility and convenience rather than the nurse's safety. While having an extra set of keys may be helpful, it does not directly address safety precautions for the nurse.
